Answer:
Option "C" is the correct answer to the following question.
Explanation:
Given:
Pressure in an automobile tire (P) = 1.88 atm
Temperature (K) = 25°C = 273 + 25 = 298 Kelvin
New temperature (K1) = 37°C = 273 + 37 = 310 Kelvin
Find:
New pressure in an automobile tire (P1) = ?
Computation:
New pressure in an automobile tire (P1) = 1.9557
New pressure in an automobile tire (P1) = 1.96 (Approx)
Answer: B
Explanation: the moon is smaller and contains less mass, therefore its gravitational pull is less than that of Earth's.
When acids react with bases they produce salt and water such as:
HCl + NaOH → NaCl + H₂O
According to strength of acid and base, we have 4 types of salts:
salt of strong acid and strong base like: NaCl
salt of weak acid and strong base like: CH₃COONa
salt of strong acid and weak base like: NH₄Cl
salt of weak acid and weak base like: CH₃COONH₄
Answer:
a substance made by mixing other substances together.
Explanation:
A mixture is a substance made by mixing two or more substances together.
<u>11.35 g</u><u> </u><u>atoms </u><u>of lead are in the sample.</u>
What does density mean?
- The density of an area refers to the quantity of things—which may include people, animals, plants, or objects—there are in it.
- Divide the number of objects by the area's measurement to determine density.
- A country's population density is calculated by dividing its total population by its area, expressed in square kilometers or miles.
We can calculate the volume of the cube by cubing the side of the cube.
Volume of cube = ( 1.000 cm)³
= 1.000 cm³
We can now determine the amount of lead in the cube by multiplying by the density. Because we know we have a 1.000 cubic centimeter and that lead has a density of 11.35 grams per cubic centimeter, we have 11.35 grams of lead.
= ( 1.000 cm³) ( 11.35 
)
= 11.35 g
