False because if the circuit performance
When we say STP that means the system is at its standard temperature and pressure. Both systems is having the same condition hence temperature and pressure is constant. We then set the amount of gas in both cases to be equal. Hence from the ideal gas law,
PV=nRT we can say that with everything constant, volume must also be constant.
The answer is (2) 2 L of methane gas.
Subatomic particles are those particles which are smaller than the atom such as electrons, protons and neutrons.
Protons are positively charged particle whereas electrons are negatively charged particle with same magnitude.
Neutrons have about the similar mass as protons but without any electric charge (neutral).
The false statement for the subatomic particles are that some atoms don't have protons: All atoms contains three subatomic particles. Every atom must have protons otherwise atom doesn't exist.
The another false statement for the subatomic particles that the protons (positively charge) and neutrons (neutral) have charges of the same magnitude.
Answer:
This equation is balanced.
Explanation:
To determine whether an equation is balanced or not, we must make sure that there are the same number of each type of atoms in both the reactants (on the left side of the equation) and the products (on the right side of the equation).
We can see that there are two atoms of nitrogen on the left side of the equation. When we look at the right side of the equation, we see that there are two molecules of NH6, with one atom of nitrogen each. Since 2 * 1 = 2, there are two atoms of nitrogen in the products as well. This means that the nitrogen atoms are balanced.
Next, we must look at the hydrogen atoms. There are 6 molecules of H2, which contains 2 atoms of hydrogen each. Since 6 * 2 = 12, there are 12 atoms of hydrogen in the reactants. On the right side of the equation, there are 2 molecules of NH6, which contains 6 atoms of hydrogen each. Since 2 * 6 = 12, there are 12 atoms of hydrogen in the products as well. Since there are 12 atoms on both sides of the equation, the hydrogen atoms are balanced.
Since both types of atoms that are presented in this equation are balanced, we can conclude that the overall equation is balanced.
Hope this helps!
Answer:
The number of valence electrons increases from top to bottom within each group.
Explanation:
The valence electrons are the outermost shell electrons.
Therefore, the number of valence electrons does not increase from top to bottom within each of the group.
Down a group, the number of valence electrons remains the same.
For group I elements, the number of electrons is 1.
The group is the vertical arrangement of elements.
From left to right across a period, the number of valence electrons increases because you move from group to group.
