What is the result of the following calculation? Record to the correct number of significant figures. 7.94 g + 0.0132 g = ?
Select one:
a) 7.95 g
b) 7.9 g
c) 7.953 g
d) 7.9532 g

Answers

I think........ a. 7.95

To solve such we need to know the concept behind significant figures. Addition, subtraction, multiplication and division follow the rules of significant figures. Therefore, the correct option is option A that is 7.95 g.

What is significant figures?

Significant figures of a number in positional notation are digits in the number that are reliable and necessary to indicate the quantity of something.

Rules for counting the significant figures are :

Zeroes before non zero digits are not significant

Zeros between non zero digits are significant.

Zeroes after non zero digits are not significant.

When we add two decimal numbers then, the final answer would be according to the number which have least significant number.

7.94 g + 0.0132 g = 7.95g

Since among 7.94 and 0.0132, 7.94  has the least significant numbers that is 3. So, answer should have 3 significant figures, answer will be 7.95.

Therefore, the correct option is option A that is  7.95 g.

Answer - What other sports can I try this spring?

Explanation:

Failures and successes are part of our daily lives as humans. It can be very challenging for one to accept his or her failures and bring oneself above it.

when failure occur, the best way to reverse the negative impacts it brings is to move forward and decide on what next to do.  

The actions that must be taken in the processes should be quite productive enough to bring back the results one desired.

When the effects of failures prove irreversible, one would then give the mind a diversion and help his or herself think their way though the failure that was encountered.

Which of the samples contains the most atoms? Use evidence from the table to explain your answer.

Answers

Answer: Sodium/Na

Explanation: Molar mass is basically a measure of how heavy 6.02 x 10^23 atoms of a substance is, measured in grams.

So, if Sodium has the lowest molar mass then that means it’s molecules are very light. I’ll give a comparison: if you have 10 kilograms of bricks and 10 kilograms of feathers, will you have more feathers or bricks? Feathers, of course.

Mathematically it looks like this

50g/22.99g/mol = 2.17 mol

2.17 mol • 6.02 x 10^23 = 1.31 x 10^24 atoms

50g/58.93g/mol = 0.85 mol

You can see that as molar mass increases that the number of moles, and consequently, atoms, decreases.

Hope this helped

The atoms and molecules in a solid are so tightly bound together that they vibrate in situ rather than moving. Liquids have a fixed volume but can flow to change their shape. Atoms and molecules are only weakly bound together in liquids.

In the water bottle, a solid is a water bottle and water is a liquid. Solids' molecules continue to be tightly packed. Solids' molecules don't move about freely in all directions; instead, they stay stationary.

The molecular formula of the liquid​ : C₆H₁₂

Further explanation

Given

molar ratio C H = 1.2 : 0.12

0.12 g at STP gave 32 cm³(0.032 L)

Required

The molecular formula

Solution

At STP, 1 mol = 22.4 L, so for 0.032 L :

mol = 0.032 : 22.4

mol = 0.00143

Molar mass (M) of liquid :

M = mass : mol

M = 0.12 g : 0.00143 mol

M = 83.92≈84 g/mol

C : H = 1 : 2

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 0.167moles are there in 12.0 g of FeO into moles.

What is mole?

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number. The stoichiometry represents the number of moles.

Mathematically,

number of moles of FeO =given mass of FeO ÷ molar mass of FeO

Molar mass of FeO  =71.8444 g/mol

mass of FeO = 12.0 g

Substituting all the given values in the above equation, we get

number of moles of FeO  = 12.0  ÷71.84

number of moles of FeO =0.167moles

Therefore, 0.167moles are there in 12.0 g of FeO into moles.

What is rate of reaction? Discuss in brief slow and fast reactions.

Answers

The reaction rate or rate of reaction is the speed at which a chemical reaction takes place, defined as proportional to the increase in the concentration of a product per unit time and to the decrease in the concentration of a reactant per unit time.

Reactions that happen quickly have a high rate of reaction. For example, the chemical weathering of rocks is a very slow reaction: it has a low rate of reaction. Explosions are very fast reactions: they have a high rate of reaction. Rate of reaction is an example of a compound measure.

What is the source of the ions involved in a redox reaction that occurs in an electrochemical cell?

Answers

Answer:

D. Electrodes

Explanation:

A redox reaction is defined as the reaction in which both oxidation and reduction reactions take place and electrons are transferred from oxidized substance to the substance that is being reduced.

An electrochemical cell is consist of electrodes (anode and cathode), electrolyte solution, salt bridge, and conducing wire. An electrochemical cell undergoes redox reaction that produces an electric current due to the movement of ions through electrodes. Electrodes are the source of ions, as anode electrode undergoes oxidation reaction and releases electrons or ions and cathode, gains electrons through reduction reaction.

Hence, the correct answer is "D. Electrodes".

Freshwater is a scarce resource, making up just around 3% of the total amount of water on Earth. Although freshwater is regarded as a renewable resource, certain areas utilize more freshwater than can be replaced by natural processes.

There is a very small amount of fresh water on Earth, making it a scarce resource. The polar ice caps and glaciers contain around 77% of the fresh water on Earth. This results in a relatively limited supply of fresh water for human use.

Explanation:

Iron metal is more reactive than copper. ... Cu is less reactive than iron, therefore, cannot replace iron from iron sulphate (FeSO4). we have already seen that iron is more reactive than copper. So that means that in this reaction, copper is less reactive than iron. That means copper cannot displace iron. It cannot kick out iron from a sulfate.

Is BaOH2 soluble or insoluble in water?

Answers

Answer:

Explanation:

Tough question.

The answer is very dependent on the temperature of the water. At 0o C, less than 5 grams is soluble in water.

The curve increases as the temperature increases. At 80oC about 35 grams  is soluble in water 100 mL of water.  So Ba(OH)2 is very soluble at higher temperatures.

Maybe the question can be resolved just a little better at room temperature. The solubility is still less than 5 grams / 100 mL. That makes it slightly soluble or more soluble than other things.

So to answer the question, you need to specify the temperature. I would say it is, but be prepared to defend your answer.
