Answer:

Precipitation reaction

Explanation:

Given that solution A was mixed with solution B, the solution turned cloudy. The test is not warm and no bubbles visible. This means that the precipiate is formed.

The concept is when two colourless solutions react to form a cloudy precipitate that settles at bottom of a solution then the reaction is said to be a precipitation reaction.

An example can be the Reaction of Silver nitrate with common salt.

A 25 kg rock is placed in a graduated cylinder with water.the volume of the fluid is 18.3ml.calculate the density of the rock in
ipn [44]

Answer:

=> 1366.120 g/mL.

Explanation:

To determine the formula to use in solving such a problem, you have to consider what you have been given.

We have;

mass (m)     = 25 Kg

Volume (v) = 18.3 mL.

From our question, we are to determine the density (rho) of the rock.

The formula:

p = \frac{m}{v}

First let's convert 25 Kg to g;

1 Kg    = 1000 g

25 Kg = ?

= \frac{25 × 1000}{1}

= 25000 g

Substitute the values into the formula:

p =  \frac{25000 g}{18.3 ml}

= 1366.120 g/mL.

Therefore, the density (rho) of the rock is  1366.120 g/mL.

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

Why a dipole develops in a molecule
Debora [2.8K]

Explanation:

When the covalent bonds in a molecule are polarized so that one portion of the molecule experiences a positive charge and the other portion of the molecule experiences a negative charge. This separation of opposite charges creates an electric dipole.
