Answer:
The answer to your question is 6
Explanation:
Data
Cu + 2AgNO₃ ⇒
To find the answer, count the number of each element in the reactants
Element Quantity
Copper 1
Silver 2
Nitrogen 1
Oxygen 6
Then, in the products, there must be 6 oxygens so in the products there must be 6 oxygens so the reaction is balanced.
Answer: 1.10x10²³ atoms of C
110202600000000000000000 atoms C
Explanation:The solution process is shown below.
0.183 mole C x 6.022x10²³ atoms C / 1 mole C
= 1.10x10²³ atoms C
or 110202600000000000000000 atoms C
Answer:
45.2g produce x mole of CH4. we are given the mass of methane. mass (CH4)=45.2g. molar mass (CH4) = 12+4 =16g/mol. Mole=mass. molar mass. mole=45.2. 16. mole=2.8mol. therefore, if 45.2g produce 2.8mol as 1 mole of methane, the water produced is 2(2.8) we Are multiplying by 2 because the water is having 2 moles water mole is 5.6mol

Answer:
1 has the highest density because it has the most amount of circles in the least amount of space- it is the most densely filled with circles; it is the most dense.
Answer:
1. Heterogeneous: Mixtures in which composition is not uniform throughout. For example, soil.
2. Homogeneous: Mixtures that have uniform composition throughout. For example, air.
3. Solute: the component of a solution which is present in smaller quantity. For example, Sugar in water
4. Solvent: the component of a solution which is pr3esent in larger quantity. For example, water
5. Solution: A solution is a homogeneous mixture of two or more substances. For example brass.
6. Mixture: When two or more compounds or elements mix up physically they from a mixture.
7. Colloid: Solutions in which particles are large and possess the characteristics of the Tyndall effect. For example milk.
8. Dissociation: the splitting of a molecule into smaller molecules is called dissociation.
9. Pure substance: A pure substance is a type of matter having definite properties.
10. Suspension: Suspensions are heterogeneous mixtures of undissolved particles. For example milk of magnesia.
11. Element: element is a substance made up of the same number of atoms.For example hydrogen
12. Compound: Compound is a substance made up of two or more elements. For example water.
