Answer:

Synthesis or combination.

Explanation:

Hello there!

In this case, according to the given chart containing the types of reactions, it turns out possible for us infer this given reaction:

____ N2+__H2→ __NH3

Is synthesis or combination, because it follows the pattern A + B --> C. Moreover, it can be balanced as shown below:

N2+3H2→ 2NH3

Calculate the percent of Cl in KClO4

sergejj [24]

Answer:

25.6 %.

Explanation:

To calculate the % of Cl in KClO₄:

<em>% Cl = [Atomic mass of (Cl)/molar mass of KClO₄] x 100</em> = [(35.5 g/mol)/(138.55 g/mol)] x 100 = <em>25.62 % ≅ 25.6 %.</em>

Volume of a gas at STP, if its volume is 80.0 mL at 1.08 atm and –12.5oC.

vodomira [7]

Answer:

90.5mL is the volume of the gas at STP

Explanation:

It is possible to find volume of a gas when conditions of temperature and pressure change using combined gas law:

$\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}$

Where P is pressure, V is volume and T is absolute temperature. 1 is initial conditions and 2 final conditions.

If initial conditions are 1.08atm, 80.0mL and absolute temperature is (-12.5°C + 273.15) = 260.65K.

And STP are 1atm of pressure and 273.15K of absolute temperature. Replacing:

$\frac{1.08atm80.0mL}{260.65K} =\frac{1atmV_2}{273.15K}$

V₂ = <em>90.5mL is the volume of the gas at STP</em>

Explanation:

First thing first, you mistyped the specific heat of water, which should be

water

4.18

∘

Now, a substance's specific heat tells you how much heat is required to increase the temperature of

1 g

of that substance by

∘

In the case of water, you would need

4.18 J

to increase the temperature of

1 g

of water by

∘

Notice that your sample of water has a mass of

1 g

as well, which means that the only factor that will determine the amount of heat needed will be the difference in temperature.

The equation that establishes a relationshop between heat and change in temperature looks like this

, where

- heat absorbed

- the specific heat of the substance, in your case of water

- the change in temperature, defined as the difference between the final temperature and the initial temperature

Plug in your values and solve for
