Answer:
75 Newton
Explanation:
In order to find the force of the object, you must remember that the equation N = (mass x acceleration). Therefore meaning you would divide 300 kilograms, <em>the mass, </em>by 4 meters per second (squared), <em>the acceleration.</em>
Answer:
The answer is in the problem
Explanation:
As general rule of number of oxygen is -2:
O → -2
Alkali metals (Li, Na, K) are always +1
Na → +1
Alkali earth methals (Be, Mg, Ca...) are always +2
Ca → +2
The halogen group (F, Cl, Br...) is always -1
F → -1
The oxidation number of Si (+/- 4)
Aluminium is, usually +3
And to complete the octet rule in nitrogen, 3 electrons are required. That means:
N → -3
Answer:
do you mean?
Explanation:
the structural formula of butyl pentyl ether
A double displacement reaction is a type of reaction in which two reactants exchange ions to form two new compounds. Many double displacement reactions occur between ionic compounds that are dissolved in water. A double replacement reaction is represented by the general equation.
M = amount of the solute / mass of the <span>solvent
0.523 = x / 2.00
x = 0.523 * 2.00
x = 1,046 moles
molar mass KI = </span><span>166.0028 g/mol
</span><span>
Mass = 1,046 * 166.0028
Mass </span>≈<span> 173.63 g
