Answer:
they are inversly related
Explanation:
As the force increases distance decreases .They are related with an equation
F= Gm1×m2/r^2
Answer:
2.78 x 10²³
Explanation:
1 mole contains 6.02 x 10²³ hydrogen atoms => 0.46 mole contains 0.46(6.02 x 10²³) hydrogen atoms or 2.78 x 10²³ atoms.
Caution => When to use H vs H₂ => This problem is specific for 'hydrogen atoms' but some may simply say hydrogen. In such cases use H₂ or 'molecular hydrogen' is the focus. it's a matter of semantics, H vs H₂.
Answer:
- smoke
- marshmallow
- paint
- Body spray
Explaination:
Firstly, what are colloids?
Colloids are a mixture of two substances:
- one of those substances are insoluble and inseparable
There are 4 types of colloids:
- Sol- Solid in a liquid
- Emulsion- Liquid in a liquid
- Foam- Gas in solid/liquid
- Aerosol- Solid/liquid in gas
So on to the answers:
- Smoke consists of solid and gas and since the solid is being carried by the gas, it is a solid in a gas (aerosol)
- Marshmellow consists of tiny air bubbles and sugar(solid), the air bubbles is inside the solid making it a gas in a solid (foam)
- Body spray turns gas into liquid after spraying it through the can, making it a liquid in a gas (aerosol)
- Paint dries up to become solid which makes it a solid is a liquid (sol)
Hope y'all understand
Answer:
320 g
Step-by-step explanation:
The half-life of Co-63 (5.3 yr) is the time it takes for half of it to decay.
After one half-life, half (50 %) of the original amount will remain.
After a second half-life, half of that amount (25 %) will remain, and so on.
We can construct a table as follows:
No. of Fraction Mass
half-lives t/yr Remaining Remaining/g
0 0 1
1 5.3 ½
2 10.6 ¼
3 15.9 ⅛ 40.0
4 21.2 ¹/₁₆
We see that 40.0 g remain after three half-lives.
This is one-eighth of the original mass.
The mass of the original sample was 8 × 40 g = 320 g
