Water breaks down into  hydrogen and oxygen: It is a decomposition reaction as a single substance decomposes to give two products.

H_2O \rightarrow H_2 +\frac {1}{2}O_2

Leaves make starch using  chlorophyll and carbon dioxide: Synthesis reaction: as the synthesis reaction involves two or more than two reactants which join together to result into a single main product along with the formation of simple by products.

6CO_2 + 6H_2O \rightarrow C_6H_{12}O_6 + 6O_2

Food burns in oxygen gas  and releases a lot of energy: Combustion: Combustion process involves the use of oxygen to give products along with release of energy.

C_6H_{12}O_6 + 6O_2\rightarrow 6CO_2 + 6H_2O

Adding vinegar (acid) to baking soda (alkali) gives  a product that is neither  acidic nor alkaline: Neutralization: acetic acid in vinegar reacts with soda (base) to give salt (neutral) and .

CH_3COOH + NaHCO_3\rightarrow CH_3COONa +H_2O + CO_2

What is the instantaneous speed of the monkey at time t=5s?
bezimeni [28]
I’m assuming we’re suppose to get some kind of graph but, Instantaneous speed is the speed that is happening right now. Like driving a car at 15k/h. The instantaneous speed of the car 15k/h. On the graph, at 5s. Wherever the line is, will tell you what the speed is.

The amplitude of a paricular wave is 4.0 m. The crest to trough distance
kozerog [31]

Answer:

The crest to trough distance = 8 m

Explanation:

Given that,

The amplitude of a particular wave is 4.0 m.

We need to find the crest to trough distance.

We know that,

Amplitude = The distance from the base line to the crest or the the distance from the baseline to the trough.

It means,

Distance from crest to trough = 2(Amplitude)

= 2(4)

= 8 m

Hence, the crest to trough distance is equal to 8 m.

An object glides on a horizontal tabletop with a coefficient of kinetic friction of 0.5. If its initial velocity is 4.3 m/s, how
Shkiper50 [21]

Answer:

Time, t = 0.87 seconds

Explanation:

Given that,

Initial velocity of the object, u = 4.3 m/s

The coefficient of kinetic friction between horizontal tabletop and the object is 0.5

We need to find the time taken by the object for the object to come to rest i.e. final velocity will be 0.

Using first equation of motion to find it as :

v=u+at

a is the acceleration, here, a=\mu g

0=u+\mu gt

t=\dfrac{u}{\mu g}\\\\t=\dfrac{4.3}{0.5\times 9.8}\\\\t=0.87\ s

So, the time taken by the object to come at rest is 0.87 seconds. Hence, this is the required solution.

One cereal bar has a mass of 37 g. What is the mass of 6 cereal bars? Is that more than or less than 1 kg? Explain your answer.
GuDViN [60]

The mass is 222g.  No, it is less than 1kg.  There are 1000 grams in a kilogram so it would be 0.222kg.  Hope this Helps :D
