Explanation:
If the density of the object is more than that of water, it will sink. Otherwise it will float. The density of water is 1 g/mL.
Substance 1,
Mass, m = 450 g, Volume, V = 90 mL
Density = mass/volume
So,
It will sink.
Substance 2,
Mass, m = 35 g, Volume, V = 70 mL
Density = mass/volume
So,
It will float.
Substance 3,
Mass, m = 24 g, Volume, V = 12 mL
Density = mass/volume
So,
It will sink.
<u>Answer: </u>The correct answer is
<u>Explanation:</u>
Exothermic reactions are defined as the reactions in which heat energy is released during a chemical reaction. In these reactions, energy of the products is less than the energy of the reactants. for these reactions are ought to be negative.
In these chemical reactions, energy term is written on the product side.
From the given chemical reactions, only one reaction satisfies the above information. The chemical reaction is:
Answer:- The speed of the satellite is 7.6 .
Solution:- It's a unit conversion problem that could be solved using dimensional analysis which is also known as train trail method.
The given speed of the satellite is 17000 miles per hour and we are asked to convert it to kilometers per second.
given:
1 Kilometer = 0.62 mile
1 hour = 3600 second
Let's use this given info and plug in the values to make the set up as:
= 7.616
We round the answer to two significant figures, since the given number(17000) has only two significant figures.
Hence, the speed of the satellite is 7.6 .
