The answer is true. I get those mixed up to
Answer:
Explanation:
Igneous rocks form on Earth’s surface where magma reaches the surface.
Igneous rocks form within Earth’s mantle where magma is typically found.
The specific heat of the metal object with a mass of 22.7g heated to to temperature of 97.0°C and then transferred to an insulated container containing 84.7 g of water at 20.5 ∘C is 0.815J/g°C
How to calculate specific heat?
The specific heat capacity of a metal can be calculated using the calorimetry equation as follows:
Q = mc∆T
Where;
Q = quantity of heat absorbed
m = mass of substance
c = specific heat capacity
∆T = change in temperature
mc∆T (water) = -mc∆T (metal)
84.7 × 4.18 × 3.8 = - (22.7 × c × -72.7)
1345.375 = 1650.29c
c = 0.815J/g°C
Therefore, the specific heat of the metal object with a mass of 22.7g heated to to temperature of 97.0°C and then transferred to an insulated container containing 84.7 g of water at 20.5 ∘C is 0.815J/g°C.

To calculate the hydronium ion concentration for a solution that has a pH of 10.61, you would do the following. Since pH=-log[H3O+]. Input the pH value and solve for [H3O+].
10.61=-log[H3O+]
-10.61=log[H3O+]
-10.61=log10[H3O+]
[H3O+]=10^-10.61
[H3O+]= 2.4547x10^-8.
