Answer: 25.5°C
Explanation: take the average of the reading i.e (25 + 26)/2= 25.5
Answer:
1.
2.
Explanation:
1.Momentum is given as the product of mass by velocity of an object.
Momentum,
m=1,500kh, v=6m/s

2.Momentum,
m=7800kg, v=30m/s

new mass=7800+800=8600
As mass is increased, so does the resultant velocity as mass is directly proportional to velocity.

Riley can either change the surface area of the object or can change the slipperiness of the material.
Answer:
Al2(SO4)3 and Mg(OH)2
Explanation:
1. Al has a charge of 3-, and SO4 of 2-
when you cross multiply the charges you get
Al2 and (SO4)3
*the reason theres a bracket around the sulfate ion is that the charge 3 is not for oxygen only, but the entire sulphate ion*
Hence, Al2(SO4)3
2. Mg has a charge of 2- and OH of 1-
again cross multiply
Mg (you dont need to add the 1) and (OH)2
again, the bracket around OH means the charge appiles to Oxygen AND hydrogen
hence, Mg(OH)2
