Answer:
The awnser is cloudy suspension.
As the microscopic droplets of one liquid are suspended in the other, it is a heterogeneous mixtures.
What are heterogeneous mixtures?
Heterogenous mixtures is defined as a type of mixture where in the composition is not uniform throughout the mixture.It consists as two or more phases. The phases are chemically distinct from each other.
As there are two or more phases present in heterogenous mixtures they can be separated by solvent extraction where in one phase is miscible with the solvent and the other phase is immiscible.
Components of a heterogenous mixtures are distinctly visible . There are two types of heterogenous mixtures, the colloids and the suspensions.These two vary with each other with respect to particle size.These are the mixture which are easy to separate out.

if 500 g of iron absorbs 22000 cal of heat, what will be the change in temperature? (specific heat of iron = 0.11 cal/gC)
Answer:
400°C
Explanation:
22,000 cal / (0.11 cal/g°C x 500 g) = 400°C
Answer:
400 C degree change
Explanation:
22 000 cal = 500 g * (C) * .11 cal / g-C
C = 22 000 / (500*.11) = 400 C degree change

What are radioactive decay series?Series (or family) of natural radioactive decay is the set of elements with unstable nuclei, which follow an orderly sequence of spontaneous decay, that is, they emit alpha and beta particles, until a stable lead nucleus is created.
In this case, natural radioactive decay occurs when the nucleus of the atom of some chemical element is unstable and then it "breaks", releasing electromagnetic radiation and disintegrating.

How do we calculate moles?The mole (symbol mol) is the SI base unit of material quantity. The amount of substance in an object or sample is a measure of how many elementary entities of a certain substance are present.
Given chemical reaction is:
[tex]2CO + O_2[/tex] → [tex]2 CO_2[/tex]
From the stoichiometry of the reaction, it is clear that 2 moles of carbon dioxide are produced.
Actual moles will be calculated by using the enthalpy and energy value as:
Actual moles of [tex]CO_2[/tex] = 275kJ × ([tex]\frac{2 mol}{566 kJ}[/tex]) = 0.97 moles.
Grams of carbon dioxide = moles X molar mass of carbon dioxide.
Grams of carbon dioxide = 0.97 X 44.01 g/mol
Grams of carbon dioxide = 42.6897 g

What is the approximate tangential speed of an object orbiting earth with a radius of 1.8 × 108 m and a period of 2.2 × 104 s? 7.7 × 10–4 m/s 5.1 × 104 m/s 7.7 × 104 m/s 5.1 × 105 m/s
This question involves the concepts of time period and tangential speed.
The tangential speed of the object is "5.1 x 10⁴ m/s".
What is the time period?The following formula gives the time period of the object:
[tex]T=\frac{2\pi}{\omega}\\\\[/tex]
[tex]\omega = \frac{2\pi}{T}[/tex]
where,
[tex]\omega[/tex] = angular speed = ?T = time period = 2.2 x 10⁴ sTherefore,
[tex]\omega=\frac{2\pi}{2.2\ x\ 10^4\ s}\\\\\omega=2.86\ x\ 10^{-4}\ rad/s[/tex]
Now, the tangential speed can be given by the following formula:
[tex]v=r\omega[/tex]
where,
r = radius = 1.8 x 10⁸ mv = tangential speed = ?Therefore,
[tex]v=(1.8\ x\ 10^8\ m)(2.86\ x\ 10^{-4}\ rad/s)[/tex]
