Anna007 [38]3 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

When the pressure that a gas exerts on a sealed container changes from 22.5 psi to ? psi, the temperature changes from 110 degre
natta225 [31]
Using Gay-Lussac's Law, pressure is proportional to (absolute) temperature in Kelvin. We first convert the temperature values to Kelvin: 110 C = 383.15 K, while 65 C = 338.15 K.
P1/T1 = P2/T2
22.5/383.15 = P2/338.15
P2 = 19.9 psi

How much heat is required to change temperature of 2g of water from 34°C to 68°C? (Water has a specific heat of 4.18)
statuscvo [17]

Answer: B

Explanation:

To find the amount of heat required, you would use q=mcΔT.

q=2g(4.18J/g°C)(68-34°C)

q=284.2 J

*Please ignore the capital A in the equation. I can't find a way to type in the degree sign into the equation without the A appearing.
