1 answer:

3 0

The hypothesis of this experiment is as follows: IF detergent A is used to wash, THEN the clothes will be cleaner.

HYPOTHESIS:

Hypothesis is commonly referred to as an educated guess. It is a critical part of the scientific method.

Hypothesis aims at providing a testable answer to a scientific question or solving a scientific problem. The hypothesis must be testable and can be accepted or not depending on the result of the experiment.

Hypothesis usually shows how the the independent variable of an experiment affects the dependent variable.

Hypothesis is written in an IF, THEN...... statement.

In this experiment to determine the type of detergent that affects the cleanliness of clothes, the hypothesis will read: IF detergent A is used to wash, THEN the clothes will be cleaner.

Amanda [17]

An inert gas will not react with either the reactants or the products, so it will have no effect on the product/reactant ratio, and therefore, it will have no effect on equilibrium.

A single serving bag of snack chips contains 65.0 Cal. Assuming that all of the energy from eating these chips goes toward keepi

AveGali [126]

Answer:

= 62.1 hours

Explanation:

Energy provide by the serving is 65 cal

= 65 cal × 4.184 Kj = 271.96 kJ

271.96 KJ = 271960 J

Energy required for 1minute of energy

= 73 x 1

= 73 J/min

So, 271960 joules will be required for 271960 heart beat

Minutes = 271960 / 73

= 3593.94 minutes

Time in hours = 3725.429 / 60

= 62.1 hours

What is the density of an object that has a mass of 6.5 g and when placed in water displaces the volume from 4.5mL to 11.8mL? ro

KengaRu [80]

Answer:

$\rho =0.9g/mL$

Explanation:

Hello,

In this case, due to the volume displacement caused the by the object's submersion, it's volume is:

$V=11.8mL-4.5mL=7.3 mL$

In such a way, considering the mathematical definition of density, it turns out:

$\rho =\frac{m}{V}=\frac{6.5g}{7.3mL}\\ \\\rho =0.89g/mL$

Rounding to the nearest tenth we finally obtain:

$\rho =0.9g/mL$

Regards.
