Answer:

Metals typically loose electrons and become cations

Explanation:

Metals are typically found towards the left hand side of the periodic table. They typically possess fewer electrons in their outermost shell compared to nonmetals.

As a result of this, when metals form chemical bonds with other elements, it is energetically more favourable for metals to loose electrons and form cations.

A block of wood has the mass of 180 grams.it is 10 cm long,6 cm wide and 4 cm thick.what is it’s density?
DochEvi [55]

Answer:

0.75 g/cm³

Explanation:

Given data:

Mass of wooden block =  180 g

Length of block = 10 cm

Width of block = 6 cm

Height or thickness = 4 cm

Density of block = ?

Solution:

Volume of block = height × length × width

Volume of block = 4 cm × 10 cm× 6 cm

Volume of block = 240 cm³

Density of block:

density = mass/ volume

d = 180 g/ 240 cm³

d = 0.75 g/cm³

There are two common oxides of copper; one is 80% copper and the other is 89% copper by weight. Calculate the formula and name e
irakobra [83]

80% copper (Cu)

Cu: 80 :  63.546 = 1.259

O: 20 : 16 = 1.25

Cu:O = 1 : 1

the formula: CuO

89% copper (Cu)

Cu: 89 :  63.546 = 1.4

O: 11 : 16 = 0.6875

Cu:O = 2:1

the formula: Cu₂O

All of the following use digitized signals to encode and transmit information EXCEPT:
eimsori [14]

Answer:

Record players

Explanation:

In a record player, a stylus vibrates as it follows a spiral groove cut into the surface of the rotating record.

The vibrations (analogue) are converted into electrical signals and fed into an amplifier to produce the sounds you hear

Fiber optic cables, Wi-Fi devices, and flat screen TVs use digitized signals to encode and transmit information

Which of the following pairs of reactants is likely to produce a pure metal when the
storchak [24]
1. Na3PO4+Mg(NO3)2= NaNO3 + MgPO4
So this is not the answer.
2. Al+CuCl2= AlCl3+ Cu
So this is the answer.
3. Mg+O2= MgO2
So this is not an answer
4. Cl2+KI= KCl+I2
So this is also an answer

Hence B and C are answers

how many mL of a 3.5 M sodium hydroxide will be needed to neutralize 15mL of a 4.3 M hydrochloric acid solution?
kobusy [5.1K]
Step 1 : write a valanced equation..
NaOH + HCl 》NaCl + H2O

Step 2 : find the number of mole of HCl..
1000 ml ..contains 4.3 mole
15ml... (4.3÷1000)×15 =...

Stem 3 : use mole ratio....
HCl : NaOH
1 : 1
So mole is same as calculated above...

Step 4 :
3.5 mole of NaOH is in 1000ml
(4.3÷1000)×15 mole is in ....
