Answer:
A. Hydrogen cans oxygen are reactants
Explanation:
Oxygen has a charge of -2. Hydrogen has a charge of +1. So it takes two hydrogens to balange the one oxygen hence the H20. So the reaction is balanced, and H20 is indeed made up of 1 oxygen and 2 hydrogen atoms. The equation 2 hydrogen + 1 oxygen (<---reactants) = Water (<--product) So hence Hydrogen cans oxygen is not a true statement. If cans is a misspelling then C would be your answer.

The speed of the yacht : 100 km/h

Linear motion consists of 2: constant velocity motion with constant velocity and uniformly accelerated motion with constant acceleration
- At constant velocity motion:
the speed of vo = v = constant
acceleration = a = 0
Δx = vt or x = xo + vt
An equation of constant velocity motion
x = distance = m
v = speed = m / s
t = time = seconds
A yacht sailed at a steady speed for 0.5 hours, and traveled 50 kilometers
so the velocity/speed:
Answer:
1
Explanation:
it is a trench so if they went together then they would rise up but if they missed then it would create a hole
The Ka is 0.0104.
To solve for the Ka, the formula is Ka = [H+][ClO-]/[HClO].
In order to determine the value of H+, the formula is H+ = 10^-pH (the pH here
is 1.80). This yields 0.015848931924611134. In the ICE table, since H+ is the same
value as ClO, then the ClO is also 0.015848931924611134. The HClO is the 0.04 -
0.015848931924611134. Substituting the values to the earlier mentioned
equation, the answer is 0.01040072606175673227903507631149 or simply, 0.0104.
For AlCl3 to be a Lewis acid, it would have to react in such a way that it accepted a lone pair from some other atom or molecule from a Lewis base.AlCl3 has an electron-deficient aluminum atom. It has only six electrons in its valence shell. It readily accepts electrons from other atoms, in an attempt to get a full valence shell of eight electrons.
