Friction of the air, and the surface it is on
Answer:
1. First
2. Third
3. Fourth
4.remain the same as
Explanation:
Given the reaction equation;
Rate= k[A] [B]^3
We can see that the order of reaction is first order with respect to reactant A and third order with respect to reactant B. This gives an overall fourth order reaction.
If the concentration of A is doubled and that of B is halved. The rate of reaction remains the same.
Answer: 3.306 mmol
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
where,
Molarity
n= moles of solute
= volume of solution in ml
According to stoichiometry:
1 mole of 
gives 2 moles of 
1.653 mmol of gives =
of
Thus number of millimoles of are 3.306
The elements in each group have<span> the </span>same<span> number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements. Every element in the first column (</span>group<span> one) </span>has<span> one electron in its outer shell.</span>
The answer to the question is D. Zinc, Gold, Aluminum, and oxygen are all elements in the periodic table
