How many molecules are 0.5000 miles of H2?

1 answer:

4 0

1 mol of wager contains 6.002 * 1023 H2O molecules. Therefore, 0.500 mol contains 0.5000 * (6.022*1023)=3.01*1023 H2O molecules.

Find the force of gravity of 1000 kg car.

ANEK [815]

Answer:

The force of gravity acting on the car is 9800 N vertically downward.

Explanation:

Given:

Mass of the car given is 1000 kg.

We know that the force of gravity is the force applied by the center of Earth on any body. The force of gravity is also called the weight of the body and always act towards the center of the Earth.

From Newton's second law, we know that the force acting on a body is equal to its mass and acceleration.

Here, the acceleration acting on the car is due to gravity and thus has a constant value of 9.8 m/s² on the surface of Earth.

Therefore, the force of gravity acting on the car is given using the Newton's second law as:

Force of gravity = Mass of car $\times$ Acceleration due to gravity.

Force of gravity = (1000 kg) $\times$ (9.8 m/s²)

Force of gravity = 9800 N [1 kg.m/s² = 1 N]

Therefore, the force of gravity acting on the car is 9800 N vertically downward.

Use the periodic table to identify each of the following bonds as polar or nonpolar.

Molodets [167]

Answer:

Polar

Step-by-step explanation:

Electronegativity increases from left to right in the Periodic Table.

Cl is further right than C (both tinted pink) in the portion of the Periodic Table below.

Cl is more electronegative than C, so the Cl has a partial negative charge and the C has a partial positive charge.

The C-Cl bond is polar.
