Explain whether changing the ratio of baking soda and vinegar changes the amount of carbon dioxide produced. Include the evidence you used to reach your conclusion.
Answers
On changing the ratio of baking soda and vinegar changes the amount of carbon dioxide produced is true, because each species will depends on both reactants.
What is chemical reaction?Chemical reactions are those reactions in which reactants are mixed with each other for the formation of new product.
Chemical reaction between baking soda and vinegar is shown below in the attached image in which the formation of carbon dioxide, water and sodium acetate takes place. So the formation of carbon dioxide depends on the baking soda and baking soda reacts with vinegar to form sodium acetate so change in the ratio will changes the amount of carbon dioxide.
Hence on changing the ratio of reactants and vinegar changes the amount of carbon dioxide.

A 100 g sample of potassium chlorate, KCIO3(s), is completely decomposed by heating:
2 KCIO3(s) 2 KCl(s) + 3 O2(g)
The oxygen is collected at 89 kPa and 23°C. Calculate the volume, in litres, of oxygen that would be
produced during the decomposition of this sample.
Answers
In order to be able to calculate the volume of oxygen gas produced by this reaction, you need to know the conditions for pressure and temperature.
Since no mention of those conditions was made, I'll assume that the reaction takes place at STP, Standard Temperature and Pressure.
STP conditions are defined as a pressure of
100 kPa
and a temperature of
0
∘
C
. Under these conditions for pressure and temperature, one mole of any ideal gas occupies
22.7 L
- this is known as the molar volume of a gas at STP.
So, in order to find the volume of oxygen gas at STP, you need to know how many moles of oxygen are produced by this reaction.
The balanced chemical equation for this decomposition reaction looks like this

Decreasing particle size
Increasing the temperature
Decreasing the temperature

Answers
Answer:
Increasing the temperature
Increasing particle size
Explanation:
Increasing the temperature allows for particles and molecules to move faster (because there is an increase in energy) and allows for more collisions.
∴ Increasing the temperature would be an answer.
Increasing the particle size allows for more surface area and a greater chance for particles to collide with each other.
∴ Increasing particle size would be an answer.

3g of clean mg ribbon and 8g of clean copper metal was burnt separately in equal volume of air and both mass reacted completely with air state and explain where they was greater change in mass??
Answers
Answer:
gshshs
Explanation:
bshsjskskehhshs
The copper metal is heated in the air. The magnesium ribbon emits a brilliant light and magnesium oxide, which is white. When oxygen is passed over copper (in the presence of heat), an oxidation reaction occurs, resulting in the formation of black copper oxide. The greater change in mass observed when they start to burned.
What is copper metal ?Copper is a mineral and an element that is essential to our daily lives. It is a significant industrial metal due to its high ductility, malleability, thermal and electrical conductivity, and corrosion resistance. It is a necessary nutrient in our diet.
Metals are a class of materials that have high electrical and thermal conductivity, as well as malleability, ductility, and high light reflection. Copper (Cu), aluminium (Al), and other metals are examples.
The combustion of magnesium ribbon is a combined reaction. This is due to the fact that magnesium reacts with oxygen to form the single product magnesium oxide. When magnesium ribbon is burned in air, it reacts with the oxygen in the air to form magnesium oxide.
Thus, 3g of clean mg ribbon and 8g of clean copper metal were burnt separately in equal volume of air and both mass reacted completely with air the greater change in mass observed when they start to burned.

You go fishing and obtain some lead weights for your trip. Since you are the smartest chemistry student
in the land, you know that lead's density is 11.34 g/mL. If there are 50 weights in a 250. mL box, what is
the mass of each weight?
Pls show work if u can!
Answers
Answer:
56.7g
Explanation:
Density = mass/volume
According to this question, some lead (Pb) of certain weights was obtained on a fishing trip. The density of lead is given as 11.34g/mL. If the 50 weights are placed in a 250. mL box, the mass of the lead are as follows:
Density = mass ÷ volume
11.34g/mL = mass/250mL
mass = 250 × 11.34
mass = 2835g
Since the 50 weight of lead weighs 2835g, then the mass of each weight is calculated as follows:
= 2835/50
= 56.7g
Aniline involves an amine, which is a Choose... functional group. When an aqueous acid solution is added to an organic solution including aniline, the aniline appears in the Choose... layer in its Choose... form. Then, a base is added to Choose... the aniline.
Answers
Answer:
Basic
Aqueous
Protonated
Reconstitute
Explanation:
Aniline contains the -NH2 group in which the hydrogen atom bears a lone pair of electrons which is capable of accepting a proton hence aniline is basic.
This lone pair makes it possible for aniline to be protonated to yield an ionic substance which enters into the aqueous phase.
Addition of a base leads to the reconstitution of the aniline.
For each pair (4), choose the stronger bond:
1. H–F (single bond) or H–Cl (single bond)
2. C–C (single bond) or C=C (double bond)

Vitamin C is a water-soluble vitamin, so your body doesn't store it. You have to get the required amount from your diet (citrus fruits are a great source!), or you could take a daily vitamin C supplement pill. Vitamin C is ascorbic acid, so to determine how much vitamin C (acid) has been placed in each pill, you could do an acid-base titration. One vitamin C pill was dissolved in water and titrated to an endpoint by 16.00 mL of a 0.447 M solution of NaOH. How many grams of ascorbic acid were there in the pill? (MW of ascorbic acid is 176.1 /mol). Explain and show your work.
Answers
Answer:
1.26 g
Explanation:
Number of moles of ascorbic acid = concentration × volume
Concentration = 0.447 M
Volume = 16.00 mL
Number of moles = 0.447 × 16/1000
Number of moles = 7.152 × 10^-3 moles
Number of moles= mass/molar mass
Molar mass of ascorbic acid = 176.1 g/mol
Mass = 7.152 × 10^-3 moles × 176.1 g/mol
Mass = 1.26 g
