Determine from the balanced chemical reaction if

Chemistry

Anna007 [38]4 years ago
8 0

Answer:

The equation is balanced

Explanation:

Before a equation can be said to be balanced the number of mole at the reaction side must be equal to number mole at the product side

Let's start with Zn at the reactant side 4 moles of Zn reacts and 4 moles of Zn was obtained from the product side which makes it balanced

Let's take HNO3

For H,10 moles react and 10 moles was obtained in the product side

For N,10 moles react and 8 moles was obtained initially and 2 moles was obtained as well which makes it 10 moles and it makes it balanced

For O,30 moles react and after calculating the total amount of O at the product side it was observed to be 30 which indicates that the equation is balanced...

The equation is absolutely well balanced

I need help on 4-6 pleasee
GenaCL600 [577]

4. It is an endothermic process. The body of someone taking a shower would be absorbing heat from the environment, another example of this would be cooking an egg

5. Ice melting is endothermic. The ice is absorbing heat from the environment, water freezing would be an exothermic reaction as it is transferring heat into the environment

6 however i do not have an answer for. I may just be a little dense but I'm not entirely sure what it is asking when it asks what the system is.

What would be the volume in liters of an 2.45 liter sample of gas at 594 °C
Ber [7]

Answer:

V_2= 1.19L

Explanation:

Hello there!

In this case, since the STP conditions are defined by 1 atm (101.3 kPa) and 273 K, it is possible for us to use the combined gas law for this problem as we are given variable pressure, temperature and volume:

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

In such a way, solving for V2 as the final volume, we obtain:

V_2=\frac{P_1V_1T_2}{P_2T_1} =\frac{156kPa*2.45L*273.15K}{101.3kPa*(594+273)K}\\\\V_2= 1.19L

Regards!
