I think it means the reaction doesn't have any intermediate phases - the order doesn't change, and it moves at the same rate, it doesn't speed up or slow down at any time

What should we do to reduce the risk when working with concentrated acids and bases
Solnce55 [7]

What should be done to reduce the risk when working with concentrated acids and bases are;

<em><u>1) Ensure that the concentrated acids and bases are stored separately in safety cabinets. </u></em>

<em><u>2) If you don't have separate safety cabinets and the must be stored in same cabinet, then you must ensure that they are stored in separate compartments. </u></em>

<em><u>3) Lastly, the separate compartments or cabinets must have their separate spill containment compounds.</u></em>

          When working with strong acids and bases during neutralization reactions, usually the production of gases can make the solution which is corrosive to splash and get to people around there.

         Due to how strong the acids and base are, these splashes from the neutralized solution could have potentially damaging effects on humans when it contacts them by either casing skin burns or even blindness.  

Now, to reduce the risk of the adverse effects stated above, what could be done is;

1) Ensure that the concentrated acids and bases are stored separately in safety cabinets.

2) If you don't have separate safety cabinets and the must be stored in same cabinet, then you must ensure that they are stored in separate compartments.

3) Lastly, the separate compartments or cabinets must have their separate spill containment compounds.

The chemical reaction for photosynthesis is 6 CO2 + 12 H2O + light
Lana71 [14]

Answer:

B. During the light reactions of photosynthesis, water is split, removing electrons and protons, and oxygen gas is released.

Explanation:

In Photosynthesis two phases occurs. They are grouped into light dependent and light independent phase (dark phase) reactions. In the light dependent phase, sunlight is trapped by chlorophyll and water is split into its components ( oxygen, hydrogen ions and free electrons; photolysis). Part of the electrons and the hydrogen ions are picked up by NADP (Nicotinamide adenine dinucleotide phosphate) converting it to NADPH and part of the electrons are used to replenished the photosystems trapping the sunlight.

A rock weighing 32.0 g is placed in a graduated cylinder displacing the volume from 12.3 mL to 16.8 mL. What is density of the r
Ierofanga [76]
Answer:
               Density  =  7.11 g.cm⁻³

Solution:

Density is given as,

                               Density  =  Mass / Volume   --------- (1)

Data Given;
                   Mass  =  32 g

                   Volume  =  16.8 mL - 12.3 mL  =  4.5 mL  =  4.5 cm³

Putting values in equation 1,

                               Density  =  32 g / 4.5 cm³

                               Density  =  7.11 g.cm⁻³
