Answer:
The CORRECT answer is Solution
Explanation:
Since a Colloid is a liquid like substance that cannot be removed from other solids the only possible choice would be a Solution. becuase with a solution you can drain the solution and still get the beans.

calculate the mass of 3.011×10^24 molecules of water...................... plzz i need it asap plzz help me plzz
Answer:
90.10 g
Explanation:
Step 1: Given data
Number of molecules of water: 3.011 × 10²⁴ molecules
Step 2: Calculate the moles corresponding to 3.011 × 10²⁴ molecules of water
We will use Avogadro's number: there are 6.022 × 10²³ molecules of water in 1 mole of molecules of water.
3.011 × 10²⁴ molecules × (1 mol/6.022 × 10²³ molecules) = 5.000 mol
Step 3: Calculate the mass corresponding to 5.000 moles of water
The molar mass of water is 18.02 g/mol.
5.000 mol × 18.02 g/mol = 90.10 g

Question 3
A milkman adds a very small amount of baking soda to fresh milk.
(a) Why does he shift the pH of the fresh milk from 6 to slightly alkaline?
Answer:
Curd is acidic in nature, because an acidic substance has less value of pH. A milkman adds a very small amount of baking soda to fresh milk. Why does he shift the pH of the fresh milk from 6 to slightly alkaline? Answer: By making the milk more alkaline, it takes more time to turn into curd.
A graduated cylinder is placed on an electronic balance, and the scale reads 78.32 g. 10.0mL of glycerine are added, and the scale reads 91.78 g. What is the density of glycerine
Answer:
1.346 g/mL
Explanation:
The density is defined as the mass of a substance per unit of volume.
In the problem, you add 10.0mL of glycerine. the mass change from 78.32g to 91.78g. The difference is the mass of the glycerine:
Mass glycerine: 91.78g - 78.32g = 13.46g
As the volume added was 10.0mL, the density, δ, in g/mL is:
δ =13.46g / 10.0mL =
1.346 g/mLHow many sig figs are in:
0.0058096

What do a hypothesis and scientific law?
Answer:
If you mean "What is a hypothesis and the scientific law?" than hypothesis means a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation and scientific laws or laws of science, are statements, based on repeated experiments or observations, that describe or predict a range of natural phenomena. The term law has diverse usage in many cases across all fields of natural science.
Answer:
If you mean "What do hypothesis and scientific law have in common" than a hypothesis is a limited explanation of a phenomenon; a scientific theory is an in-depth explanation of the observed phenomenon. A law is a statement about an observed phenomenon or a unifying concept.

An experiment performed to determine the density of lead yields a value of 10.95 g/cm3. The accepted value for the density of lead is 11.342 g/cm3. Find the percent error.
Answer:
3.45618%
Explanation:
Percent Error = measured value - accepted value/ accepted value x 100
Measured Value: 10.95
Accepted Value: 11.342
Work:
[tex]\frac{10.95-11.342}{11.342} *100[/tex]
[tex]\frac{-0.392}{11.342} *100[/tex] = -3.45618
You cannot have a negative percentage. Therefore the answer is 3.45618%

How many joules of heat are needed to raise the temperature of 10.0 g of aluminum from 22°C to 55°C, if the specific heat of aluminum is 0.90 J/g°C?
Answer:
0.90 degree C
Explanation:
The key to this problem lies with aluminium's specific heat, which as you know tells you how much heat is needed in order to increase the temperature of 1 g of a given substance by 1∘C
In your case, aluminium is said to have a specific heat of
0.90 J g∘ C.
Please please help :(
Answer: ¹²₅C
Explanation:
¹²₅C is incorrect. The superscript is the atomic mass. This varies between each element. The subscript is the atomic number. This doesn't change. You will see every element has the correct atomic atomic number except for Carbon. Carbon should have atomic number 6.

plz tell me I will also give brainiest. forces can be ________ or unbalanced
Answer:
balanced
Explanation:
hope this helps
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{ \: Balanced}}}}}[/tex]
Explanation:
Forces can be balanced or unbalanced.
[tex] \bigstar {\sf{ \: \: Balanced \: force}}[/tex]
When a number of forces acting on a body do not change its state of rest or uniform motion in a straight line , the forces are said to be balanced forces. For example : In the game of tug of war, two teams pull a rope in opposite directions. When the two teams exert equal and opposite forces on the rope, the rope remains steady and does not move in any direction. It appears as if no force is acting on the rope. Thus, the two forces acting on the rope in this case are balanced forces.
[tex] \bigstar{ \sf{ \: Unbalanced \: force}}[/tex]
When a number of forces acting on a body change it's state of rest or uniform motion in a straight line, the forces are said to be unbalanced forces. For example, if we push a toy car towards east, it moves towards east. If it is pushed towards west, it moves towards west. This unbalanced force produces motion.
Hope I helped!
