Answer is: John Dalton proposed that matter is made of tiny particles.
Proust's law or law of constant composition said that a given chemical compound always contains its component elements in fixed ratio and does not depend on method of preparation.
Water (H₂O) is made of two hydrogen atoms and one oxygen atom:
m(H) : m(O) = 2·1 : 16 = 1: 8.
Dalton said that matter is composed of atoms and atoms of different elements can join to form chemical compound.
Sewer lice is a living organism.
All species are "(aq)" unless marked otherwise:
molecular: Na3PO4 + 3 AgNO3 → Ag3PO4(s) + 3 NaNO3
total ionic: 3 Na{+} + PO4{3-} + 3 Ag{+} + 3 NO3{-} → Ag3PO4(s) + 3 Na{+} + 3 NO3{-}
net ionic: PO4{3-} + 3 Ag{+} → Ag3PO4(s)
K2SO4(aq)+Na2CO3(aq) no reaction
molecular: Pb(NO3)2 + Na2CO3 → PbCO3(s) + 2 NaNO3
total ionic: Pb{2+} + 2 NO3{-} + 2 Na{+} + CO3{2-} → PbCO3(s) + 2 Na{+} + 2 NO3{-}
net ionic: Pb{2+} + CO3{2-} → PbCO3(s)
molecular: BaCl2 + 2 KOH → Ba(OH)2(s) + 2 KCl
total ionic: Ba{2+} + 2 Cl{-} + 2 K{+} + 2 OH{-} → Ba(OH)2(s) + 2 K{+} + 2 Cl{-}
net ionic: Ba{2+} + 2 OH{-} → Ba(OH)2(s)
Answer:
The study of the human body as a machine for the performance of work has its foundations in three major areas of study—namely, mechanics, anatomy, and physiology; more specifically, biomechanics, musculoskeletal anatomy, and neuromuscular physiology. Explanation:
Supersonic flight over land is typically forbidden to minimize disruption to people on the ground. This meant that until it was over open water, Concorde could not operate at its maximum Mach 2 capability.
<h3>What is Concorde?</h3>
- The Concorde is a tailless aircraft with a drooping nose, an oval delta wing, and a narrow fuselage that allows for seating for 92 to 128 passengers.
- It's improbable that Concorde will ever fly for an airline again in a commercial capacity. The economics of reactivating Concorde and incorporating it into the fleet of a contemporary airline would be challenging to justify, even if the technical and regulatory concerns could be handled.
- Supersonic flight over land is usually not allowed to minimize the impact on people on the ground. This meant that Concorde could not operate at its maximum Mach 2 speed until it was over an open body of water.
