Be sure to answer all parts. Butane gas is compressed and used as a liquid fuel in disposable cigarette lighters and lightweight

Salsk061 [2.6K]

Answer:

The correct answer will be "4.60 g".

Explanation:

The given values are:

Volume of Butane = 7.96 mL

Density = 0.579 g/mL

As we know,

⇒ $Mass \ of \ Butane = Density\times Volume$

On putting the estimated values, we get

⇒ $=0.579\times 7.96$

⇒ $=4.60 \ g$

Which of the following elements will form negative ions? Check<br> all that apply.

AleksandrR [38]

Answer:

Explanation:

Elements on the right side of the periodic table are very likely to form negative ions -- all of those except elements in the 8th or 18th column (depending on how your periodic table is numbered).

K and Mg are on the left side, so they will not form negative ions.

They give up 1 (for K) electron and 2 (for Mg) electrons which will leave plus charges for the ions.

On the other hand S and I are on the right side of the periodic table. They will take on electrons and hence be charged with a minus.

2 H2 + 2 NO → N2 + 2 H2O the observed rate expression, under some conditions, is: rate = k[NO]2 Which of the following mechanism

guapka [62]

Explanation:

Rate law is defined as the rate of a reaction is directly proportional to the concentration of reactants at constant temperature.

$Rate \propto [\text{concentration of reactant}]^{n}$

= k $[\text{concentration of reactant}]^{n}$

where, k = rate constant

n = order of reaction

For the given reaction, $2H_{2} + 2NO \rightarrow N_{2} + 2H_{2}O$

Hence, its rate will be as follows.

Rate = $k[H_{2}][NO]$

Also, it is known that slowest step in a chemical reaction is the rate determining step.

Hence, for the given rate law correct reaction is as follows.

Step 1 : $H_{2} + NO \rightarrow N + H_{2}O$ (slow)

Balancing this equation it becomes $H_{2} + 2NO \rightarrow N_{2}O + H_{2}O$ (slow)

Step 2: $N_{2}O + H_{2} \rightarrow N_{2} + H_{2}O$ (fast)
