Neon I think. Go to the periodic table and see which one is the 11th
Answer:
B. Write the chemical equation using formulas and symbols.
D. Count the atoms in each substance in the reactants and products,
Explanation:
When balancing chemical equation, it implies that the law of conservation of matter be strictly adhered to.
By so doing, the number of atoms on both sides of the reaction must be the same. Number of atoms in the products and reactants must have the same value.
- It is always a good approach to first write the chemical equation of the reaction.
- This will give an overview of the reacting species and the products being formed.
- Then, go on to count the number atoms in the reactants and product sides of the expression.
- Then balance it using any of the method of balancing chemical equations.
Answer:
Mass of the water is equal to the mass of ice
Explanation:
When ice melts, the mass remains the same even though its volume decreases leading to a decrease in density of water.
The mass remains the same because according to the law of conservation of mass, mass can neither be created nor destroyed. Since mass is neither created nor destroyed in the process of melting, the mass of water must remain the same.
Answer:
Summary. Water molecules are polar, so they form hydrogen bonds. This gives water unique properties, such as a relatively high boiling point, high specific heat, cohesion, adhesion and density.
