Answer:
3
Explanation:
Nonmetals are only on the right side (other than hydrogen of course).
Malleable means to be able to be hammered out of shape with no cracking and luster is shiny (metallic properties)
Most likely a transition metal
Answer:
You haven't given enough information, you have to tell us how many grams of which reactant are present, as well as the initial and final temperatures of the solution.

Answer:</h3>
pH = 8.66
<h3>
Explanation:</h3>
- The pH refers to the acidity or alkalinity of a solution.
- It is calculated by getting the negative logarithm of Hydrogen ions concentration.
In this case;
we are given [OH⁻] as 4.6 x 10^-6 M
We are required to calculate the pH
We need to know that;
pH + pOH = 14
pOH = -log[OH⁻]
To get the pH we can calculate the pOH first,
pOH = -log[4.6 x 10^-6 M]
= 5.34
but, pH + pOH = 14
Therefore, pH = 14 - pOH
= 14 - 5.34
= 8.66
Therefore, the pH of the solution is 8.66

Answer:
4,000 Kilojoules (2 sig. figs. based on 2 sig. figs. in 75Kg water).
Explanation:
Energy change equation => q = m·c·ΔT
q = total amount of heat flow
m = mass in grams = 75,000 grams
c = specific heat of water = 4.184 joules/gram·°C
ΔT = Temperature change in °C = 22.4°C - 9.8°C = 12.6°C
q =(75,000g)(4.184j/g·°C)(12.6°C) = 3,953,880 joules = 3,954 Kilojoules ≅ 4,000 Kilojoules (2 sig. figs. based on 2 sig. figs. in 75Kg water).
