Advanced science 7 grade 7.

can anyone me with this science question soon as possible? i want the correct answers.

consider the following chemical equation and then answer the questions below:

c3h8 + 5o2 > 3co2 + 4 h2o

1. how many carbon atoms are present on the reactant side?

2. how many hydrogen atoms are present on the product side?

3. how many carbon atoms are present on the product side?

4. how many oxygen atoms are present on the product side?

5. how many oxygen atoms are present on the reactant side?

6. is this chemical equation balanced?

7. how many hydrogen atoms are present on the reactant side?

According to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? view available hint(s) according to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? trigonal bipyramidal tetrahedral square planar determination of electron geometry requires information on whether the electron groups are lone pairs or bonding groups.

Movement that is like a t a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. transfers energy from one location to another a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
