It’s called Carbon Tetraflouride or ( Monocarbon Tetraflouride )

I hope that the answer is correct ☺️

This compound contains these two nonmetal elements: carbon (C) and fluorine (F). Since this compound only contains two types of nonmetal elements, we will be using Type 3 naming (for binary compounds).

In type 3 naming we use prefixes for the second element named (in this case, fluorine) and the first element (carbon) is just left alone.
So, since we have four fluorine atoms, the prefix will be "tetra." Also, we turn the "ine" in fluorine into "ide"

So here is the name: carbon tetrafluoride.

(Note that carbon tetrafluoride is also known as: tetrafluoromethane)

Explain how changes in temperature affect the particle motion of a substance.

Travka [436]

When the temperature increases, warms, or heats up the molecules become excited. Their movement becomes faster and they tend to move far apart from other molecules.

when nahco3 completely decomposes, it can follow this balanced chemical equation: 2nahco3 → na2co3 h2co3 determine the theoretic

AnnZ [28]

Using stoichiometry, 3.24 grams $NaHCO_{3}$ will yield 2.04 grams $Na_{2} CO_{3}$ and 1.20 grams $H_{2} CO_{3}$ . But in an actual decomposition where the mass of one of the products was measured to be 2.01 grams, which is $Na_{2} CO_{3}$ , the percent yield is 98.34%.

Stoichiometry is defined as the relationship between the amounts of substances that are involved in chemical reactions.

Mole ratio relates the amounts in moles of any two substances by looking at the coefficients in front of each species in the balanced chemical equation.

For the decomposition of $NaHCO_{3}$ , it follows the balanced chemical equation:

$2NaHCO_{3} = Na_{2} CO_{3}+H_{2} CO_{3}$

2 moles of $NaHCO_{3}$ will decompose into 1 mole of $Na_{2} CO_{3}$ and 1 mole of $H_{2} CO_{3}$

mole ratio = 2 : 1 : 1

If the mass of $NaHCO_{3}$ sample is 3.24 grams, then

molar mass = m/n

84.007 g/mol = 3.24 g/n

n = 0.03856821455 mol $NaHCO_{3}$

and using the mole ratio 2 : 1 : 1, theoretically,

0.03856821455 mol $NaHCO_{3}$ will yield 0.01928410728 mol $Na_{2} CO_{3}$ and 0.01928410728 mol $H_{2} CO_{3}$ .

If there's 0.01928410728 mol $Na_{2} CO_{3}$ , its mass is:

molar mass = m/n

105.9888 g/mol = m/ 0.01928410728

m = 2.043899389 g $Na_{2} CO_{3}$

On the other hand, if there's 0.01928410728 mol $H_{2} CO_{3}$ , then

molar mass = m/n

62.03 g/mol = m/0.01928410728

m = 1.196193174 g $H_{2} CO_{3}$

If the mass of one of the products was measured to be 2.01 grams, then it must be $Na_{2} CO_{3}$ since the experimental value is much closer to the theoretical mass.

Calculating its percent yield,

percent yield = actual yield/theoretical yield x 100%

percent yield = 2.01 g/2.043899389 g x 100%

percent yield = 98.34143552% = 98.34%

What kind of chemical reaction does the chemical equation sodium plus chlorine equal sodium chloride represent

Nadya [2.5K]

The answer is synthesis. This is a kind of reaction in which numerous reactants mix to make a single product. Synthesis responses discharge energy in the way of heat and light, so they are exothermic. An instance of a synthesis reaction is the creation of water from hydrogen and oxygen.

Hope I could help!
