How can you minimize a collision summary

1 answer:

4 0

One of the ways to minimize a collision is to slow down: When you can't find an escape and you're definitely going to collide with something, you should slow your vehicle down as much as possible.

Hope this helps ^^

What is the ph of a solution of 0.550 m k2hpo4, potassium hydrogen phosphate?

Solnce55 [7]

We assume that we have Ka= 4.2x10^-13 (missing in the question)
and when we have this equation:
H2PO4 (-) → H+ + HPO4-
and form the Ka equation we can get [H+]:
Ka= [H+] [HPO4-] / [H2PO4] and we have Ka= 4.2x10^-13 & [H2PO4-] = 0.55m
by substitution:
4.2x10^-13 = (z)(z)/ 0.55
z^2 = 2.31x 10^-13
z= 4.81x10^-7
∴[H+] = 4.81x10^-7
when PH equation is:

PH= -㏒[H+]
= -㏒(4.81x10^-7) = 6.32

A correct statement of Henry's law is: a. The concentration of a gas in solution is inversely proportional to temperature. b. Th

AVprozaik [17]

Answer:

e. None of these.

Explanation:

Hey there!

In this case, since the Henry's law is defined in terms of pressure, henry's constant and pressure, as shown below:

$C=K_H*P$

Whereas C is the concentration, KH the Henry's constant and P the pressure, we infer that the concentration of a gas solution is directly proportional to the pressure, which is not the group choices, therefore, the answer is e. None of these.

Best regards!

Analyze complete and balance the following equation co2(g)+hcl(aq)

Anna007 [38]

Answer:

$CO_{2} (g)+4HCl(aq)->2H_{2} O(g)+CCl_{4} (g)$

This is a double displacement reaction, C goes with Cl in the products side and O2 goes with H. All that is left is to balance the equation, making sure each side has equal amounts of atoms.
