fomenos4 years ago
8 0

Answer:

1}800m/s

2}80m/s²

Explanation:

1]first convert the kilometers to meters so as to obtain similar units;

16×1000=16000m   (1Km=1000m)

then divide the ditance by time:

speed=distance/time  

=16000m/2s

=800m/s

2]acceleration=(initial velocity -final velocity)/time taken

=(800m/s-0m/s)/10s

=800m/s/10s

=80m/s²

ch4aika [34]
I think that you have put up an incomplete question. However, i am answering the question based on my research and knowledge. 

Lissa- accuracy and precision are both low
Lamont- accuracy and precision are definitely high
<span>Leigh Anne- accuracy is low but precision is definitely high.

What is the difference between an atom an ion how to determine the charge
Eduardwww [97]

Explanation:

When an atom's outermost orbital gains or loses electrons (also known as valence electrons), the atom forms an ion. An ion with more protons than electrons carries a net positive charge and is called a cation. An ion with more electrons than protons carries a net negative charge and is called an anion

For the reaction N2(g) + 3H2(g) 2NH3(g), what will happen if hydrogen gas was removed from the reaction mixture? There will be a
Hoochie [10]
This uses something called <span>Le Chatelier's principle. It states essentially that any stress put upon a system will be corrected.

In more simple terms, it means that in an equilibrium, such as the equation N2(g) + 3H2(g) <=> 2NH3(g), removing a reactant will cause the system to create more of said reactant to compensate for its loss, or adding excess reactant will cause the system to remove some of the added reactant. For future reference, the same principle applies to products in an equilibrium as well. 

In this case, hydrogen gas is a reactant, and hydrogen is being removed. According to </span><span>Le Chatelier's principle, the system will shift to create more hydrogen gas. In essence, it will shift in the direction of the hydrogen gas, so there will be a shift toward the reactants.

To clear something up, Keq will not change, as it is a constant value with constant conditions (such as temperature, pressure, etc.).</span>
