The empirical formula of the compound is called the formula unit in chemistry. In 1.5 moles of magnesium bromide, [tex]9.03\times 10^{23}[/tex] formula units are present.

Moles are the measuring units of the molecules, atoms, and other particles of the chemistry. Formula units of any substance can be estimated as the product of the moles and the Avogadros number.

The number of the moles present of the magnesium bromide is 1.5 mol and the value Avogadro number is [tex]6.02 \times 10^{23}.[/tex]

If 1 mole of the substance contains [tex]6.02 \times 10^{23}[/tex] formula units, then, formula units in 1.5 moles are:

[tex]\begin{aligned} & = 1.5 \times 6.02 \times 10 ^{23}\\\\& = 9.03 \times 10^{23} \end{aligned}[/tex]

Therefore, [tex]9.03 \times 10^{23}[/tex] formula units are present in 1.5 moles of magnesium bromide.

Ecosystem services are indispensable to the wellbeing of all people, everywhere in the world. They include provisioning, regulating, and cultural services that directly affect people, and supporting services needed to maintain the other services.

Ecosystem provides water and air which are essential for survival on earth without the presence of these essential things life on earth could not exist.

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Answer:

C. The behavior of an organism is not influenced by either its heredity or its environment.

Answer:

B

Explanation:

Explanation:

Moles of N2 = 35.0g / (28g/mol) = 1.25mol

Moles of H2 = 60.0g / (2g/mol) = 30.0mol

Since 1.25mol * 3 < 30.0mol, nitrogen is limiting.

Moles of NH3 = 1.25mol * 2 = 2.50mol.

Mass of NH3 = 2.50mol * (17g/mol) = 42.5g.

30.0mol - 1.25mol * 3 = 26.25mol.

Excess mass of H2

= 26.25mol * (2g/mol) = 52.5g.

Answer:

Answer:

Second order

Explanation:

We could obtain the order of reaction by looking at the table very closely.

Now notice that in experiment 1 and 2, the concentration of [OH^-] was held constant while the concentration of [S8] was varied.  So we have;

a situation in which the rate of reaction was tripled;

0.3/0.1 = 2.10/0.699

3^1 = 3^1

Therefore the order of reaction with respect to  [S8] is 1.

For [OH^-], we have to look at experiment 2 and 3 where the concentration of [S8] was held constant;

x/0.01 = 4.19/2.10

x/0.01 = 2

x = 2 * 0.01

x = 0.02

So we have;

0.02/0.01 = 2^1

2^1 = 2^1

The order of reaction with respect to  [OH^-] = 1

So we have the overall rate law as;

Rate = k[S8]^1  [OH^-] ^1

Overall order of reaction = 1 + 1 = 2

Therefore the reaction is second order.

Answer:

Milk

Explanation:

Main compounds of milk are lactose and casein. And it is also called a colloidal mixture (i.e. in which one substance of microscopically dispersed insoluble or soluble particles is suspended throughout another substance). Therefore milk is regarded as a mixture not as a pure substance. So this is the required answer.

Answer:

V = 12.5 L

Explanation:

Given data:

Volume of NO = 15.0 L

Temperature and pressure = standard

Volume of nitrogen gas produced = ?

Solution:

Chemical equation:

6NO + 4NH₃    →     5N₂ + 6 H₂O

Number of moles of NO:

PV = nRT

n = PV/RT

n = 1 atm × 15.0 L / 0.0821 atm.L /mol.K × 273.15 K

n = 15.0 atm.L / 22.43 atm.L /mol

n = 0.67 mol

now we will compare the moles of No and nitrogen gas.

              NO           :         N₂

               6             :          5

              0.67         :         5/6×0.67 = 0.56

Volume of nitrogen gas:

 PV = nRT

1 atm × V = 0.56 mol ×  0.0821 atm.L /mol.K × 273.15 K

V = 12.5 atm.L / 1 atm

V = 12.5 L

For the well balanced equation of photosynthesis

Answer:

25N

Explanation:

The force calculated to be 25kgm/s² has a value of 25N.

To solve this problem, we need to consider the unit of force. The unit of force is expressed in N, newtons.

  To find force;

           Force  = mass x acceleration

            Unit of mass  = kg

                      acceleration  = m/s²

 So;

        1N  = 1kgm/s²

Therefore 25kgm/s² is the same as 25N

Answer:

b- 232%

Explanation:

Renewable energy consumption by energy source in 2006 = 6.659 quadrillion Btu

Renewable energy consumption by energy source in 2010 = 8.049 quadrillion Btu.

In 2006, wind energy = 4%

∴ wind energy = 4% x 6.659 = 0.26636

In 2010, wind energy = 11%

∴ wind energy = 11% x 8.049 = 0.88539

∴ Percent increase = (final number - initial number) ÷ (initial number) x 100

% increase = [(0.88539 - 0.26636) ÷ 0.26636} x 100 = 232.4035% ≈ 232%.

Answer = 232%.
