Answer:
REFRACTION IS THE BENDING OF A WAVE AS IT PASSES AT AN ANGLE FROM ONE MEDIUM TO ANOTHER. WHEN A WAVE MOVES FROM ONE MEDIUM TO ANOTHER, THE WAVE'S SPEED CHANGES. WHEN A WAVE ENTERS A NEW MEDIUM AT AN ANGLE, THE PART OF THE WAVE THAT ENTERS FIRST BEGINS TRAVELING AT A DIFFERENT SPEED FROM THE REST OF THE WAVE.

Answer:
Volume of flask = 29.134 cm³
Explanation:
Mass of water = mass of filled stoppered flask - mass of empty stoppered flask.
Mass of water = 65.858 - 36.724 = 29.134 g
Density of water = 1 g/cm³
Volume = mass/ density
Volumeof water = 29.134 g/ 1g/cm³ = 29.134cm³
Therefore, volume of flask = 29.134 cm³

Answer:
116.88 g
Explanation:
Step 1: Write the balanced equation for the synthesis of NaCl
Na + 1/2 Cl₂ ⇒ NaCl
Step 2: Calculate the moles corresponding to 45.978 g of Na
The molar mass of Na is 22.990 g/mol.
45.978 g × 1 mol/22.990 g = 1.9999 mol
Step 3: Calculate the number of moles of NaCl formed from 1.9999 moles of Na
The molar ratio of Na to NaCl is 1:1. The moles of NaCl formed are 1/1 × 1.9999 mol = 1.9999 mol.
Step 4: Calculate the mass corresponding to 1.9999 moles of NaCl
The molar mass of NaCl is 58.443 g/mol.
1.9999 mol × 58.443 g/mol = 116.88 g
Based on the picture, the way that chemical bonds form in the substance is :
K loses an electron and Br gains an electron.
This created difference in charges, which create attraction
hope this helps
