Answer:
plants take carbon dioxide out of the atmosphere and use the energy from sunlight to combine the carbon dioxide and water to form sugar and oxygen
Answer:
Check explanation section.
Explanation:
Yes, that is true. Sodium with chemical symbol Na belongs to the group 1 on the periodic table. Group 1 elements are known as Alkali metals. Other elements in the group are Caesium, lithium, Rubidium, francium and potassium.
Neon belongs to the noble gas of group 8/0.
Sodium is very reactive and and good conductor of electricity. Sodium reacts with water for the production of hydrogen (NB: this reaction is vigorous).
2Na(s) + 2H2O ------------> 2NaOH + H2(g).
They can react with nonmetals such as the halogens. For instance;
Na + Cl2 -------------------------------> 2NaCl.
Sodium is ductile and have low melting point( but high compared to neon).
Neon is not active chemically and it has no odour and no color
Answer:
The plum pudding model of the atom agreed with the nuclear model
Explanation:
Answer:
[H+] =5.62*10⁻¹⁰
Explanation:
pH = 9.25
The formula to find pH of a solution is
pH = -Log[H+]
9.25 = -Log[H+]
Take the anti log of both sides
[H+] = 10⁻⁹.²⁵
[H+] = 5.62*10⁻¹⁰
The concentration of Lithium Hydroxide is 5.62*10⁻¹⁰
