I am Lyosha [343]3 years ago
5 0

Answer:

1) combustion

2) double replacement

3) combination

4) combustion

Explanation:

The combustion of a compound refers to the reaction of that compound with oxygen to produce heat and light. In reactions (1) and (4) above, ethanol and methane reacted with oxygen to yield carbon dioxde and water. This is a combustion reaction.

Reaction(2) is a double replacement reaction because the both cations exchange their anion partners in the product.

Reaction (3) is a combination reaction. It involves the joining of two elements to form a new compound.

A laboratory bottle of helium gas occupies a volume of 2.0 L at 760 mm Hg. Calculate the new pressure if the
Fantom [35]

Answer:

<h2>844.4 mmHg</h2>

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

P_1V_1 = P_2V_2

Since we are finding the new pressure

P_2 =  \frac{P_1V_1}{V_2}  \\

From the question we have

P_2 =  \frac{2 \times 760}{1.8}  =  \frac{1520}{1.8}  \\ =  844.4444...

We have the final answer as

<h3>844.4 mmHg</h3>

Hope this helps you

In this equation, stands for carbon, stands for nitrogen, and stands for oxygen. Which equation represents this reaction?
Marat540 [252]
In order to answer this question we must look at the image which I have attached.

The red atoms refer to oxygen atoms, the grey atoms are carbon atoms and the blue atoms are nitrogen. Therefore, the equation from the image suggests:

2CO + 2NO → 2CO₂ + N₂

Looking closely at the options given, several of them could be eliminated immediately since they are not balanced equations like B, C and E. Therefore, only A or D could be the answers.

The answer is option <span>D.) 2CO + 2NO → 2CO2 + N2
