The methyl salicylate (wintergreen oil) is the methyl ester of salicylic acid.
Methyl salicylate is produced by esterifying salicylic acid with methanol, the reaction scheme is attached to this answer. In the past, it was commonly distilled from the twigs of Betula lenta (sweet birch) and Gaultheria procumbens (eastern teaberry or wintergreen).
Answer:
a) Graph
b) Weight balance or gas syringe or upside-down measuring cylinder
Explanation:
a) Identifying a trend in temperature change over time - The best tool for this scenario is to represents the temperature daily, weekly, monthly or annually on graph to interpret the fluctuation in temperature owing to local seasonal changes and weather conditions
b) Measuring the mass of a product of a chemical reaction - If the product is solid or liquid then the balance is used to measure the mass. If the product is a gas, then gas syringe or upside-down measuring cylinder is used.
Answer:
Light energy, water and carbon dioxide
Explanation:
First, let’s look at the photosynthesis equation:
light energy + water + carbon dioxide —> glucose + oxygen
The reactants are what go in and are used to create the products.
In photosynthesis, light energy from the sun, water and carbon dioxide are used to make glucose and oxygen.
Therefore, the reactants are light energy, water, and carbon dioxide.
<span>1. The two qualities used to describe winds are direction and speed.
2. a local wind that blows during the day from an ocean toward land is a(n) sea breeze.
3. The increase in cooling that wind can cause is called the wind-chill factor.
4. Temperature differences between the equator and poles produce convection currents.
A movement that is parallel to Earth's Surface is called wind and a local wind is that wind that blows over a short distance.</span>
