Which force acts an an object to move it from rest or a constant, straight-line motion?

Chemistry

Answer:

C. Unbalanced

Explanation:

A force which can change the state of an object by changing it's speed, position or direction of motion is known as an unbalanced force. It is the resultant of all forces which are acting on a body and causing a change in the state of rest of motion of the body.

Assume a box is resting on the floor. The forces acting on the box in the rest are Normal (by the ground on the box) in upward direction and gravitational force Mg (due to gravity). Although these two forces are acting on the box, it is still in rest because these forces are balanced to each other. When we pull or push the box by applying appropriate force, the box will start to move because the force applied by us is unbalanced and there is no any force in the opposite direction to make this force balanced.

How many grams of Cl are in 525g of CaCl2
Tema [17]

First we determine the moles CaCl2 present:

525g / (110.9g/mole) = 4.73 moles CaCl2 present 

Based on stoichiometry, there are 2 moles of Cl for every mole of CaCl2:<span>
(2moles Cl / 1mole CaCl2) x 4.73 moles CaCl2 = 9.47 moles Cl </span>

Get the mass:<span>
<span>9.47moles Cl x 35.45g/mole = 335.64 g Cl</span></span>

Can somebody explain step by step how to solve decomposition reactions?
SVEN [57.7K]
A decomposition reaction occurs when one reactant breaks down into two or more products. It can be represented by the general equation:

AB → A + B
In this equation, AB represents the reactant that begins the reaction, and A and B represent the products of the reaction. The arrow shows the direction in which the reaction occurs.

AIDS is one disease caused by a virus infection. The virus attacks immune system cells known as T cells.
VLD [36.1K]

Answer:

yes,its true

Explanation:

I just want to say first off

the immune cell known as T cell also known as white blood cells

Since the first main attack from the bodies response against a virus is deploying T cells to attack

CD4 cells are the basic T cells and HIV virus which is AIDS will start to "Eat itself inside" Ofc not they will use protein spikes to form their way in

they start to create copies of themselves inside the T cell itself and creating a new protein called Env to form their ways in ofc

They are able to bypass CD4 cells is because its a basic cellular receptor for T cells making them really deadly

They now will start to attack other white cells and deploying more and more of their virus cells
