Answer:

The correct answer is gas.

Explanation:

Gas has the highest energy in the state of matter due to how freely the molecules move. Solid matter is extremely compact, having the particles very close together and not creating a lot of movement. Without having action, there is no energy.

Hope this helps! :)

Answer: 3 H₂O

Explanation:

This is an example of a common chemical reaction

ACID + CARBONATE --> SALT + WATER + CARBON DIOXIDE which implires

CITRIC ACID + SODIUM BICARBONATE ----> SODIUM CITRATE + WATER + CARBON DIOXIDE .

The full chemical equation is given by

H3C6H5O7(aq) + 3NaHCO3(aq) --> Na3C6H5O7(aq) + 3CO2(g) + 3H2O(l)

The reaction produces a fizz due to the release of carbon dioxide which can be also seem when an Alka-Seltzer® tablet is dissolved in water.

A 52.0 g of Copper (specific heat=0.0923cal/gC) at 25.0C is warmed by the addition of 299 calories of energy. find the final tem

Leto [7]

Answer : The final temperature of the copper is, $87.29^oC$

Solution :

Formula used :

$Q=m\times c\times \Delta T=m\times c\times (T_{final}-T_{initial})$

where,

Q = heat gained = 299 cal

m = mass of copper = 52 g

c = specific heat of copper = $0.0923cal/g^oC$

$\Delta T=\text{Change in temperature}$

$T_{final}$ = final temperature = ?

$T_{initial}$ = initial temperature = $25^oC$

Now put all the given values in the above formula, we get the final temperature of copper.

$299cal=52g\times 0.0923cal/g^oC\times (T_{final}-25^oC)$

$T_{final}=87.29^oC$

Therefore, the final temperature of the copper is, $87.29^oC$

Answer:

Half life = 79.67 sec

Explanation:

Given that:

k = $8.7\times 10^{-3}\ s^{-1}$

The expression for half life is shown below as:-

$t_{1/2}=\frac{\ln2}{k}$

Where, k is rate constant

So,

$t_{1/2}=\frac{\ln2}{8.7\times 10^{-3}\ s^{-1}}$

$t_{1/2}=114.94252\ln \left(2\right)\ sec=79.67\ sec$

Half life = 79.67 sec
