Answer:

1.35g of CaCO₃ are in the paracetamol

Explanation:

Assuming the volume of the 0.5mol NaOH was 23cm³

The CaCO₃ of paracetamol reacts with HCl as follows:

CaCO₃ + 2HCl → CO₂ + H₂O + CaCl₂

When an excess of HCl is added and titrated, we can find the moles of HCl that react = Moles CaCO₃ based on the second reaction:

NaOH + HCl → H₂O + NaCl

Moles added of NaOH:

23cm³ = 0.023L * (0.5mol / L) = 0.0115 moles NaOH = Moles HCl in excess

Moles of HCl:

25cm³ = 0.025L * (1.0mol / L) = 0.025 moles HCl

The moles of HCl that reacted = Moles CaCO₃ are:

0.025 moles - 0.115 moles = 0.0135 moles CaCO₃

The mass of CaCO₃ -Molar mass: 100.09g/mol- is:

0.0135 moles CaCO₃ * (100.09g/mol) =

The position where a Period 4 element that is also a metal with three valence electrons would be located is: B) Position 15.

A periodic table can be defined as an organized tabular array of all the chemical elements, which is typically arranged in order of increasing atomic number or number of protons (in rows).

In Chemistry, a periodic table comprises seven (7) rows and eighteen (18) columns. Also, all chemical elements are arranged (grouped) on the periodic table based on their atomic number (number of protons).

In this context, the position where a Period 4 element that is also a metal with three valence electrons would be located is Position 15 on the periodic table.

Answer:

A. How much decay happens in each flashlight

Explanation:

In an experiment, the DEPENDENT OR RESPONDING VARIABLE is the variable that responds to changes being made to another variable called Independent variable. It is the variable that is measured by an experimenter.

In this question, an experiment was carried out to research the effect of sunlight on plastic decay. Three plastic flashlights were used for this experiment in which one was placed in a dark closet (control), and the others were placed in light at different times or intervals. However, the variable being measured or assessed is the decay of each flashlight. This means that "HOW MUCH DECAY HAPPENS IN EACH FLASHLIGHT" is the dependent variable.

Answer:

133.74 L

Explanation:

First we convert the given pressures and temperatures into atm and K, respectively:

Then we use the PV=nRT formula to calculate the number of moles of helium in the balloon, using the data of when it was on the ground:

Then, knowing the value of n, we use PV=nRT once again, this time to calculate V using the data of when the balloon was high up:

Answer: 37.01 moles (mol) of gas

Explanation:Use PV=nRT

which is also equal to n=PV/RT

P=2.90

V= 4.80

R = 8.31 (R will always be the same in any equation)

T= 62.0

2.90 x 4.80= 13.92 / 8.31 x 62= 515.22

13.92/13.92=515.22/13.92

n= 37.01 mol

5. 2+

Explanation:

1. it qualifies under the octet rule and is completely stable.

2. 1 because  it fills every shell and has one left over

3. each time an element like oxygen bonds it can be surrounded by 8 electrons in order to be stable and each line that you may see counts as two electrons so it can have 1 bond line in each direction.

Answer:

A. Water

Explanation:

Virtually every known substance can be referred to as MATTER, as long as it has weight and occupies space. Matter can exists in three different forms namely: solid, liquid and gaseous states.

However, each state of matter has its own unique property that characterizes it. WATER is the only matter that can exists in the three different states as follows:

- LIQUID - WATER

- SOLID - ICE

- GASEOUS - STEAM OR VAPOUR.

Answer:

1. It will take the shape of its container. Particles can move about within a liquid, but they are packed densely enough that volume is maintained. Gaseous matter is composed of particles packed so loosely that it has neither a defined shape nor a defined volume. A gas can be compressed

2.  However after pouring the water from one short glass into a tall glass,  to be the same amount after being poured into any other container

3. Yes, wood have a fixed shape. Explaination: The reason is that it's solid and solids have a definite volume and shape. ... They have shapes that do not change and volumes that can be measured

4. Water is known to exist in three different states; as a solid, liquid or gas. Clouds, snow, and rain are all made of up of some form of water. A cloud is comprised of tiny water droplets and/or ice crystals, a snowflake is an aggregate of many ice crystals, and rain is just liquid water

5. Solids are sometimes formed when liquids or gases are cooled; ice is an example of a cooled liquid which has become solid. Other examples of solids include wood, metal, and rock at room temperature

6. For example, water commonly exists in three states of matter: solid (ice), liquid (water), and gas (steam)

Explanation:

plzzzzzzzzzzzzzz give brainly

1. It will adopt its container's shape. Within a liquid, particles can move around, yet the volume is maintained because of the liquid's dense packing. Particles in gaseous stuff are arranged so haphazardly that neither their shape nor their volume can be determined.

The term liquid is defined as substance which is not solid but which flows and can be poured and take a shape of container. water is an example of liquid.

2. However, the same amount of water would be poured into any other container after being transferred from one short glass to a tall glass.

3. The shape of wood is fixed. It's solid, and solids have a distinct volume and shape, which explains why. They have measurements-able volumes and unchanging forms.

4. There are three recognized states of water: solid, liquid, and gas. Snow, rain, and clouds are all composed of water in some way. A snowflake is an accumulation of several ice crystals, a cloud is made up of microscopic water droplets and/or ice crystals, and rain is just liquid water.

5. When liquids or gases are chilled, solids can occasionally form; ice is an example of a cooled liquid that has solidified. At room temperature, solids also include wood, metal, and rock.

6. As an illustration, water typically exists in three states: solid (ice), liquid (water), and gas (steam).
