Pick the slime up with your hands; it will be a little sticky. Knead the slime by stretching it out, then squishing it back together. Keep doing this for a few minutes until the slime is no longer sticky. If the slime is still sticky, then add 1/4 teaspoon of contact saline solution and knead it again.

There are a few things you can do to make slime less sticky. You can either:
1) add a bit of baking soda (one to three tea spoons depending on how big it is, for the one that you show I would say one should be enough)
2)You can place it in hot water and squish the water out of it before placing it in cold water and then drying it out a bit with a towel. Don't forget to knead it a bit so it stays smooth and not too hard.

How many grams of silver nitrate will be needed to produce 8.6 g of silver?

konstantin123 [22]

Answer:

13.5g of AgNO3 will be needed

Explanation:

Silver nitrate, AgNO3 contains 1 mole of silver, Ag, per mole of nitrate. To solve this problem we need to convert the mass of Ag to moles. Thee moles = Moles of AgNO3 we need. With the molar mass of AgNO3 we can find the needed mass:

<em>Moles Ag-Molar mass: 107.8682g/mol-</em>

8.6g * (1mol / 107.8682g) = 0.0797 moles Ag = Moles AgNO3

<em>Mass AgNO3 -Molar mass: 169.87g/mol-</em>

0.0797 moles Ag * (169.87g/mol) =

<h3>13.5g of AgNO3 will be needed</h3>

A rock is believed to have been formed 1.25 billion years ago, as calculated by using potassium-40 dating. If the half-life of p

Leya [2.2K]

Answer:

The answer to the question is

50 % of the original amount of potassium 40 will be left after one half life or 1.25 billion years

Explanation:

To solve the question we note that the half life is the time for half of the quantity of substance that undergoes radioactive decay to disintegrate, thus

we have

half life of potassium 40 K₄₀ = 1.25 billion years

To support the believe tht the rock was formed 1.25 billion years ago we have

$N_{(t)} =N_{(0)} (\frac{1}{2}) ^{\frac{t}{t_{\frac{1}{2} } } }$

After 1.25 billion years we have

$N_{(t)} =N_{(0)} (\frac{1}{2}) ^{\frac{1.25billion}{1.25 billion} } } }$ = $N_{(t)} =N_{(0)} (\frac{1}{2}) ^{1 } } }$ =0.5 of $N_{(0)}$ will be left or 50 % of the original amount of potassium 40 will be left

Ans with solution...

Licemer1 [7]

Answer:

The answer to your question is:

Vol of NO2 = 11.19 L

Vol of O2 = 2.8 L

Explanation:

Data

N2O5 = 56 g

STP T = 0°C = 273°K

P = 1 atm

MW N2O5 = 216 g

Gases law = PV = nRT

Process

216 g of N2O5 ---------------- 1 mol

54 g ----------------- x

x = (54 x 1) / 216

x = 0.25 mol of N2O5

2 mol of N2O5 ----------------- 4 mol of NO2

0.25 mol ------------------ x

x = (0.25 x 4) / 2 = 0.5 mol of NO2

V = nRT/P

V = (0.5)(0.082)(273) / 1 = 11.19 L

2 mol of N2O5 ----------------- 1 O2

0.25 N2O5 ---------------------- x

x = (0.25 x 1) / 2 = 0.125 mol

Vol = (0.125)((0.082)(273) / 1 = 2.8 L
