A double replacement is when the reactants switch with their opposite charge. For example, AB + CD = AD + BC.
In this case the given is K2SO4 + Pb(NO3)2 = ____ + ____
The answers is PbSO4 and KNO3 would expect the products of this reaction.
Answer:that sugar dissolves faster in a warm liquid than in a cool
Explanation:
Molecular diffusion, often simply called diffusion, is the thermal motion of all (liquid or gas) particles at temperatures above absolute zero. The rate of this movement is a function of temperature, viscosity of the fluid and the size (mass) of the particles. Diffusion explains the net flux of molecules from a region of higher ... Diffusion of solvents,
Answer:
its called TAXON0MY
Explanation:
they are classified in eight steps namely doma!n, k!ngdom, phylum, class, order, family, genus, and spec!es
but sometimes we do not include doma!n
if you want to name an organism you use both the genus group and the spec!es group
Example:
The scientific name for humans like us is h0m0 sap!ens
H0m0- This is our genus group
sap!ens- This is our spec!es group
sorry for using the exclamation mark it means i
Answer:
From this solution, you can do the a number question answer.
Answer:
9.4g
Explanation:
Given parameters:
Volume of hydrogen gas at STP = 15L
Unknown:
Mass of solid lithium = ?
Solution:
The reaction equation is shown below;
2Li + 2H₂O → 2LiOH + H₂
To solve this problem, lets work from the known to the unknown. The known here is hydrogen gas;
At STP;
number of moles = = = 0.67mole
From the balanced reaction equation;
1 mole of hydrogen gas is produced from 2 moles of Li;
0.67 moles of hydrogen will be produced from 0.67 x 2 = 1.34moles
Mass of solid lithium = number of moles x molar mass
= 1.34 x 7
=9.4g
