Si se disuelven 20 ml de alcohol en 80 ml de agua ¿cuánto es el % de alcohol en la solución ?

Suppose 2.2 g of hydrochloric acid is mixed with 1.61 g of sodium hydroxide. Calculate the maximum mass of sodium chloride that

kaheart [24]

Answer:

We can produce 2.35 grams sodium chloride

Explanation:

Step 1: Data given

Mass of hydrochloric acid = 2.2 grams

Molar mass of hydrochloric acid (HCl)= 36.46 g/mol

Mass of sodium hydroxide = 1.61 grams

Molar mass of sodium hydroxide = 40.0 g/mol

Step 2: The balanced equation

HCl + NaOH → NaCl + H2O

Step 3: Calculate moles HCl

Moles HCl = mass HCl / molar mass HCl

Moles HCl = 2.2 grams / 36.46 g/mol

Moles HCl = 0.0603 moles

Step 4: Calculate moles NaOH

Moles NaOH = 1.61 grams / 40.0 g/mol

Moles NaOH = 0.0403 moles

Step 5: Calculate the limiting reactant

NaOH is the limiting reactant. It will completely be consumed (0.0403 moles). HCl is in excess. There will react 0.04025 moles. There will remain 0.0603 -0.0403 = 0.0200 moles

Step 6: Calculate moles sodium chloride

For 1 mol HCl we need 1 mol NaOH to produce 1 mol NaCl and 1 mol H2O

For 0.0403 moles NaOH we'll have 0.0403 moles NaCl

Step 7: Calculate mass NaCl

Mass NaCl = moles NaCl * molar mass NaCl

Mass NaCl = 0.0403 moles * 58.44 g/mol

Mass NaCl = 2.35 grams

We can produce 2.35 grams sodium chloride

Hello<br><br><br> WRITE CAUSES AND CONSEQUENCE OF ANY 2 NATURAL CALAMITIES.

-Dominant- [34]

Answer:

1) eathquake

earthquake is the natural calamities where there is the vertical and horizontal shaking of the

earth crust. it is cause due to overlappibg of the different plates that are present in the earth surface. when this plates intersect or expand the earth occurs

consequences are it causes loss of life and human property , degards the environment , it leads to flood, landslides etc The damage caused by earthquakes is from ground shaking, ground rupture, landslides, tsunamis, and liquefaction.

Next - volcanic eruption

its is the out flow of the larva from the inner of the earth to other surface. it is cayse due to high pressure exerted on the surface of the earth that leads to explode the inner larva.

its consequences are it degards the environment and loss of the beauty of the nature , there is loss of human life , widlife , etc. volcanic eruption include infectious disease, respiratory illness, burns, injuries from falls, and vehicle accidents related to the slippery, hazy conditions caused by ash. When warnings are heeded, the chances of adverse health effects from a volcanic eruption are very low.

The measured value 24.00 g has an uncertainty of?

Orlov [11]

Answer:

±0.005 g

Explanation:

The uncertainty depends on whether the measurement was obtained manually or digitally.

1. Manual

The minimum uncertainty is ±0.01 g.

It may be greater, depending on random or personal errors

2. Digital

Most measurements of mass are now made on digital scales.

A digital device must always round off the measurement it displays.

For example, if the display reads 20.00, the measurement must be between 20.005 and 19.995 (±0.005).

If the measured value were 20.006, the display would round up to 20.01.

If the measured value were 19.994, the display would round down to 19.99.

The uncertainty is ±0.005 g.

The scale shown below would display a mass of 20.00 g
