A 15.9 g sample of sodium Carbonate is added to a solution of acetic acid weighing 20 g. the 2 substances react, releasing carbon dioxide gas to the atmosphere and water. after reaction, the contents of the reaction vessel weighs 29.3 g. what mass of carbon doixide was released into the atmosphere during the reaction?
Answer:
hope that helps
Explanation:
The total mass of reactants taken = 15.9 + 20.0 = 35.9 gm. From the conservation of mass the final mass of the contents of the vessel should also be 35.9 gm. But it is only 29.3 gm. The difference is due to the mass of released carbon dioxide gas.Hence the mass of carbon dioxide gas released = 35.9 – 29.3 = 6.6 gm

A student was measuring the ratio of a circle’s circumference and diameter. They found the circumference to be 6.28 cm and the diameter to be 1.8 cm. The actual ratio (circumference divided by diameter) was 3.14. What was their percent error?
Answer:
Percent error = 11%
Explanation:
Given data:
Circumference = 6.28 cm
Diameter = 1.8 cm
Actual ratio of circumference and diameter = 3.14
Percent error = ?
Solution:
Formula:
Percent error = ( measured value - actual value / actual value) ×100
Measured value:
Measured ratio of circumference and diameter = 6.28 cm/1.8 cm
Measured ratio of circumference and diameter = 3.49
Now we will put the values in percent error formula.
Percent error = (3.49 -3.14 / 3.14) ×100
Percent error = (0.35 / 3.14) ×100
Percent error = 0.11×100
Percent error = 11%

Which of the following is a covalent compound?
A BaCl2
(B) CHO
c) LiOH
D KNO3

Answer:
(B) CHO
Explanation:
A covalent bond is a bond type usually formed between non-metals that have little to no electronegativity differences between them.
Bonds between metals and non-metals are usually ionic in nature. All the other given choices are ionic and a combination of covalent bond.
CHO contains non-metals that are electronegative. There will be sharing of electrons between these atomic species and this will lead to a covalent bond.

12. Determine the mass in grams of each of the following.
a. 6.35 mol Al
b. 52.4 mol P
Please help❤️
Answer:
1 mole is equal to 1 moles Al, or 26.981538 grams.
Explanation:
171.3327663
1623.0250764
The mass in grams of the following is required.
The mass of Al is 171.323 g.
The mass of P is 1622.8 g.
M = Molar mass of Al = 26.98 g/mol
n = Number of moles = 6.35 mol
Mass is given by
[tex]m=nM\\\Rightarrow m=6.35\times 26.98\\\Rightarrow m=171.3\ \text{g}[/tex]
The mass of Al is 171.323 g.
M = Molar mass of P = 30.97 g/mol
n = Number of moles = 52.4 mol
Mass is given by
[tex]m=nM\\\Rightarrow m=52.4\times 30.97\\\Rightarrow m=1622.8\ \text{g}[/tex]
The mass of P is 1622.8 g.

La etiqueta de una botella de vino indica que tiene una concentración de 14,5% v/v. ¿Cuál es el volumen (soluto) en mL de alcohol contenido en una copa que se llena con 75 mL (disolución) de vino?
Answer:
El volumen de alcohol contenido en una copa que se llena con 75 mL (disolución) de vino es 10.875 mL
Explanation:
El Porcentaje Volumen a Volumen o Porcentaje en Volumen (%v/v) es una medida de la concentración que indica el volumen de soluto por cada 100 unidades de volumen de la solución. Es decir, es una medida de la concentración de una sustancia en una solución que expresa la relación del volumen del soluto con el volumen total de la solución.
El Porcentaje Volumen a Volumen de una disolución es determinada por la siguiente expresión:
[tex]v/v=\frac{volumen soluto}{volumen disolucion} *100[/tex]
En este caso:
%v/v= 14.5volumen soluto= ?volument disolucion= 75 mLReemplazando:
[tex]14.5=\frac{volumen soluto}{75} *100[/tex]
Resolviendo:
[tex]volumen soluto=\frac{14.5*75}{100}[/tex]
volumen soluto= 10.875 mL
El volumen de alcohol contenido en una copa que se llena con 75 mL (disolución) de vino es 10.875 mL

A color
B temperature
C shape
Answer: temperature

If you see a hot red ball then you know the color, red, and the shape, a ball, but you don’t know it’s hot.
The property of matter that you cannot observe just by looking at an object will be temperature.
What is matter?Matter can be defined as everything that has mass as well as volume (takes up space). It is pretty straightforward to illustrate that most typical objects which we deal with everyday basis possess mass as well as take up too much space.
It is known that if we look any matter , the physical appearance of any matter can be determined by its color and shape not with temperature.
Therefore, the correct answer will be option B.

Explanation:
how many molecules of oxygen gas (O2) are in 8 grams of oxygen
The number of molecules in the 8 grams of oxygen gas is equal to 1.506 × 10²³.
What is Avogadro's number?The Avogadro constant is denoted [tex]N_A[/tex] and is the proportionality factor that is the number of constituent particles such as atoms, or ions in one mole of a substance.
Avogadro's number is a constant with a numeric value of 6.022 × 10²³ reciprocal moles. Avogadro's number is named by scientist Stanislao Cannizzaro after the Italian scientist Amedeo Avogadro.
Given, the mass of the oxygen gas = 8 g
The number of molecules of one mole of oxygen gas = 6.022 × 10²³
The molecular mass of one mole of oxygen gas = 32 g
It means 32 g of the oxygen gas has molecules = 6.022 × 10²³
Then 8 grams of oxygen gas will have molecules = (8/32) × 6.022 × 10²³
= 1.506 × 10²³
Therefore, the molecules of oxygen gas are 1.506 × 10²³.
