DO STUFF!!! XD but really you would record there heartbeat per minute and record there normal rate and the rate watching sports!
Answer:
Bronsted lowry base = Proton acceptor = H2O
Bronsted lowry acid = Proton donor = HF-
Explanation:
The equation is given as;
HF-(aq) + H2O(l) --> F-(aq) + H3O(aq)
A bronsted lowry base is any specie that can accept hydrogen ion (proton) from another molecule.
Basically a bronsted lowry base is a proton acceptor while a bronsted lowry acid is a proton donor.
In the reaction above, upon comparing both the reactants and products;
Bronsted lowry base = Proton acceptor = H2O
Bronsted lowry acid = Proton donor = HF-
Answer:
10 ms-1
Explanation:
Kinetic energy = 1/2 × m × v^2
1 = 1/2× 20 ×10^ -3 × v^2
v ^ 2 = 100
v = 10 ms-1
note : convert grams in to kg before substitution as above
This is the sample answer:
Gravity pulls objects toward Earth at a rate of 9.8 m/s2<span>. Weight is the result of gravity's pull on a mass on Earth's surface.

Oxygen and hydrogen don't have the same eletronegativity. Oxygen is greater so it hogs the the electrons when a covalent bond occurs. After the sharing of elections, the compound is neutrals. Oxygen became slightly negative and hydrogen became slight positive.
